R & B Germany wiring tool, nail puller

[Zrxrunner]

Anyone see one like this? Labeled germany and number 6. Also has a crown symbol with R & B in it. Ive tried searching a bit with no luck. Very solid tool, well made. Jaws actually arent very sharp and almost seems like they were designed like that, possibly used to crimp or twist wire without cutting it? Has a little nail puller integrated into one of the grips.

Lots of tools like this were sold for opening crates in the old days. Crates were made of wood, with thin planks for enclosing the structure, which was used both to support the contents and provide a place to hold the nails fastening the planks. Sometimes the crates were banded with steel strapping as well.
