I have this on me most days, along with several small tools on my keychain and a rotating selection of Benchamde, Kabar, Gerber small folders.
On this Vic, I bought it from a local distributor. They said it's an Alox Bantam???
UPDATE: Just browsed and found out a scan of ye olde SA catalogue (from the 1970s !!!). Apparently the above model is 2231 s+ (old numbering system pre-1982).
Did I get a bargain for collector's item here?
