Two Tone RBN Mounted frog Ki marked

[joryfreeburg]

Here is the second really neat late war frog that I picked up recently. The two tone leather is really neat to me along with rivet holes with no rivets only stitching. It’s RBN numbered and also Ki marked. I think it’s a really cool frog. Any comments would be great! Anyone ever run across a frog similar to this?

Have never seen that Ki marking but these rest looks lovely, big fan of the brown loop.

Strange is there are not any rivets attached. Ki or Kl in circle stamp.

Nice piece. Frog is from the maker W. H. Stolla's Söhne, K & A Stolla, in Wien. The RBNr is always stamped lengthwise in this manner. Have couple of these including those with the off color brown retention strap. Possibly the four rivets have been removed? Unsure why, or perhaps never installed. My examples have rivets. I believe the circular Ki marking to be that of the leather provider. My thoughts only .....

Yes thats a Stolla Wien code.
