I don't know which seller your talking about, but Romania is an untapped source for razors, as is many Eastern Block countries.
Why,,, well,, this is a guess,,,1. The vintage straight razor market is/was not well known. 2. Collectors there are few & far between.
So, who is going to supply the rest of us with vintage straights that are just lying in drawers all over Eastern Europe?

I compare the situation to vintage radios. In 2000 I was in Romania & found myself staring at one of the nicest RCA console radios I had ever seen. The kind that our parents used to sit in front of & listen too, before T.V.s were the norm. When I expressed my love for it, I was laughed at & told, "Those junk radios are in every house & barn." I asked what she thought it was worth. She gave me a price of about $10.00 , if I remember correctly. That radio, after a power change/adapter, would have easily brought over $300.00.

Maybe Romania has produced a collector who monitors the market.
