Hi All,
I think this one was always black without any green felt. The maker mark reads "Friedrich Becker & Co.K.G. Berlin SW68" in what is best described as dunkel gelb, with 'Original "VUPA" ' in red. There is also a red dot above the marking, which looks like it was applied with a finger tip. The liner is marked '57' on one of the rear tabs.
I've never taken the front plate off, because the nuts holding it on are very tight and I don't see any evidence that there were other plates on it. The chinstrap posts are brass, rather than the silver I'd expected (some of which had those little squared loops on them)...
Yes, I agree about the chin strap and it had me scratching my head a bit, but from what I can see is that two straps have been modified and combined into one; both have the same hardware and stitching, but the embossing is deeper on the left half than right. I don't know if this was in service this way or not and it's another "you need a photo" type thing. It is easier to unsnap the strap to lower it, but it still needs to be adjusted to fit under the chin (no, I didn't... ). I really can't say why anybody would do this, except to say if they used the strap (which I've never seen photos of), then it is easier to get off with the snap. The leather on the strap and liner is supple with only light wear, and everything fits the helmet well... so I don't really know, but I like it!
Also, there is just a little black paint on the bear at the center of the plate, but I'm not going to replace the paint that may be missing... since I'm not sure if it's paint or crud in there.
But, yeah, fun to get something like this in Berlin... I just wish I could've found a Garde Reiter in Dresden, outside of their wonderful museums!
