Good luck as that looks to be quite a project!
Was sure I had a point when I started this post...

Well, back in Belgium, The 12x60 from Germany has arrived and is in the project queue for work.
Overall the paint job is the worst of it so far. I have no idea how so many of these came to be painted black, unless it was some sort of de-mil program after the war.

These are early models, this is indicated from the red, natural rubber mask pieces. Unfortunately there is no real way to deal with this. Replacement, not that there are any, would take away from the history of what they are.

Also they have no trokenluft ports, which it seems came into being later in the war.

From an external look-e-see, the glassware seems to be in good order, but the objective doublets are a little grubby and need cleaning.
The filter mechanism is intact and functional.

The eye relief adjustment screw has been sawn off, leaving a stub in place, better than the last one though (I hope)

The cover for one of the reticle alignment ports is missing.

The mounting locking knob is seized.

It has a 'homebrew' mounting plate fitted underneath

The ocular cover plate and strap is missing

For the missing parts, I have some spares, The adjustment screw, I have some repro spares I had made from last time. So this weekend I shall lift the optical carrier plate and have a look at the guts of this thing

*** NEW PROJECT ***

Just bought these, from Germany, the seller wanted 1500 GBP for them, I beat him down on that considerably, and even then I was being generous.

As you can see, they need a lot of work, but they appear to be an late model from the type of rubber used in the eye relief mask, cant read the serial number yet, so not sure.

They are in a pretty ropy cosmetic condition. Again the eye relief adjustment screw is missing, its been cut off this time. The ocular cover and strap assy is missing, the ID plate is missing.The doublets look OK, you cant tell with the oculars until you get them off and take a close look, but it does not seem to have any sign of impact damage externally. Prisms are generally robustly mounted, so most likely will be OK. There is what looks like a 'homebrew' mounting plate fitted on the base. Can't see internally from the photos what the rust situation will be, bound to be some. You may note that there are no trokenluft ports on the sides of the optical carrier plate, which again leads me to a late war conclusion.

So another tear down and rebuild job to be done.

Well the proper pintle pins have arrived from the UK. I was supposed to pick them up, but had to have them posted instead.

Also the replacement, up-sized adjustment screw arrived and has been fitted.

Well I have a friend in Italy who finds a lot of stuff for me. Currently he's in lockdown so that has kind of put everything on hold.

But he's catching up on repairing really, really old violins. And staying away from the infected, sounds like the Zombie Apocalypse.. Just waiting for the first one to show up.

Glad you like them. sometimes I wonder as for a site called Optics talk, there does not seem to be much talk.

Don't have large format optics needing work at the moment, several smaller ones under way, ROSS and Barr & Stroud mostly.

Still keeping my eye out for Japanese WW2 stuff and Italian as I don't any in my collection. Its a matter of getting lucky on price and condition.

Don, seriously, the amount of work and research you have put into these historical optics projects is truly amazing! You've amassed a tremendous amount of knowledge of the subject matter along the way! Outstanding work!

I always enjoy reading your posts, sir! Cheers!

Here they are mounted on the tripod in the glorious Belgium sunshine ready to target enemy aircraft.

Finished, at last!

When I get a moment I will set them up on a tripod and mounting outside and take a quick walk round video

As they were received:

As they are now

Here they are in the final paint finish, German Ordnance Tan, two coats on top of the primer. Now waiting for them finish curing. Dry to the touch at the moment.

Partially reconstructed the facemask.

So here is all the metal work primed up and ready for the next stage of painting.

I used gray etching primer, it looks a little darker in the photo than it really is.

Well both good news and bad.

The old broken adjustment screw has been removed. but the internal thread was so damaged, I have had to re-drill and tap the hole again. to 10mm, 1.25. This means its oversized for the replacement screw, so it looks like I am going to have to fit a helicoil insert to bring back to size again, 8mm, 1.25  or get a new screw made for this set.

It does mean that I can blank off the opening for the moment and get on with the painting at least.

This video is showing how the new eye relief adjustment screw fits. Testing to see it it fits OK, using a spare Optical carrier tray I have.

The original is shown as well for comparison, but this has a slight bend making it stiff when turning.

The new one fits well

It was from my CAD drawing, but not the one I posted, that was for a Pintle pin, which still in the workshop, they had hoped to have them ready to collect, but no luck. Anyways I told them there was no urgency on this.

I had five of the replacement screws made, thought might as well, what would be the point of just one, which I am going to use anyway?

The 70+ year old original I will keep safely in a box.

Looks good Don. Is that the one machined from your CAD drawing?

This is one of the new, repro eye relief adjustment screws that I have had made.

Rubbish phone photo, but you get the idea. For the clueless, the new one is on the top.

So now I have to prime it with etching primer and then paint and grease it ready to install in the binocular body, then finally I can get on with the painting.

If you get offered any COVID-19, 'JUST SAY NO!'

Yes, I made a solution in my garden, in the rain (well it wasn't raining when I started) under a tarpaulin.

Tried doing it in the kitchen. Bad idea, really bad idea. Wife had several comments on the subject.

Cat gave me a dirty look as well. Good job the Daughter was not around else I would have ticked the 'Pissed off the whole family' box.
