Hi Marco, 

could have been the Biometar. I recall reading about it in Prochnow's Rollei Report, but I don't have that at hand now.

And it doesn't have those silly focussing tabs Leitz has on their lens. I much prefer a focussing ring you can actually grab. My lens are 2nd hand and black though, and so look a bit odd on the old silver Leicas. Been looking to replace them with silver ones, but they show up less often on eBay.
