As both us suspect, is likely a nice reproduction. Dial is stressed to make it look old. A genuinely old one would bring a handsome price. One recently auctioned was bid extremely high until someone questioned about a certain bushing and whether it was plastic. The seller replied that it was plastic and all the high bidders retracted their bids and finally sold much lower. I suspect perhaps SELVA made this and perhaps 1970s. Appears to have a passing strike and probably with two wheels, very short duration. Nice acquisition. I've never had one of these but feel certain I could make it work.
