Hi all,

This Ruka Rathenow SS 6X30 dienstglas is my latest collection, I'd like to hear your opinons, thanks! Yun

those look very early. And the process for applying maker and serial number and dienstglas marking was different than the later glass. These are raised and not stamped or engraved into the plates. Im not sure how this was accomplished ? weather the image was struck from behind or acid applied? Im really not sure.

To answer you're question. I for one like the markings. They look correctly applied for the period. This early process is even harder to fake. I.M.H.O.

Hi MAUSER99,
I am interested in having more info about these SS-Dienstglas marked binos.
This pair also looks nice to me.
Are these plates made of brass?
Were the early ones all made like this?
What would be the give away signs of fakes?
Thanks!

Mine are 101xxx serial range and plates are aluminum. I like yours.

This is the correct original early binoculars RUKA SS.
Stamps are filled with low-melting metal.
Good condition! Congratulations on a wonderful adding to the collection!

Yes the markings are bulging and not engraved into the plates. I have seen another Ruka SS binos on WAF before, the markings are different with mine, and the serial number are 6 digits, that's why I am curious.

Thanks Andy
The binos are fairly good though the leather cover on the right grip was broken.
Further opinions are welcome!

the method used for applying the maker and diensglas Ect. has nothing to do with them being SS or Ruka. this was the early process that was changed. It may have had something to do with the material change from brass to Aul. ? I always wondered how the early hallmarks were applied. I figured reversed stamped. ??

Yes, this is due to the reduction in the cost of production and the change of materials from brass to aluminum.
All manufacturers in the late 30s switched to aluminum.
For a new marking used stamps and sometimes engraving.

It may just be the angle that the first photos were taken but to me it seems that the objective lens's are coated?if that is the case then they are not right

[Sgt Bilko]

I've noticed the same effect in pictures of binoculars I've bought. Turns out that sometimes the cement between the doublets give the impression, from certain angles, of being coated. I think they look good but, even if they are coated, there's no saying what happened post war. I've a 1930's Zeiss Septarem and a 1930's Barr and Stroud that both had coated objectives fitted post war

Both of the objective and ocular lenses are not coated. The "coating" on the lens you saw in previous picture is the reflection of blue sky

You mean some of the early binoculars were disassembled and re-coated post war?

[Sgt Bilko]

Nice Tartan - "Royal Stewart" if I'm not mistaken. As to coated objectives - I think many top manufacturers offered to replace the objectives with coated ones after the war.

No other parts of my Barr and Stroud (a "private purchase one - not royal Navy owned) or my Septarem (a "donated to the war effort" then sold publicly) are coated - only the objectives.....
