Curious about a Lens: Rossal 125mm f4.7 ?

I am looking into some vintage glass in the 125mm range and came across a lens I’d never heard of before. Does anyone have any info on the Rossal 125mm f4.7?

Found one for sale on a big auction site that comes with copal 0 shutter. Appears to be a vintage design (very compact) but in a more recently released build?

I've never heard of it either but it is definitely a tessar, and the seller is completely wrong stating it is a wide angle, and the asking price is WAY above it's value.
