The barrelflat- the first item here - shows Belgian proofmark for 1937, the Czech import mark shows a year which I can not decipher.
Holecek was a retailer in Hradec Kralove, who had a second outlet
in Dvur kralove nad labem.The serial number of the gun coincides
with other Defourny-numbers I have seen over the years.
I have a catalogue of Holecek (in Czech language) and an additional promotional flyer. I have started to compile stuff for an article on LOVENA to appear in the DGJ, but please be very patient. It is a matter with many loose ends, which need to be closed.
Kind regards
