Unfortunately Merkel has no wartime work cards according to them. Found several Merkel catalogs it is either a 128e or a special order variant of the 128e. Consensus both here and over there is that it’s only the second Merkel Droplock found, the other one was the same gun (actual gun not just the model)pictured in the catalogs. It’s definitely the top of the food chain. I consider myself Lucky to be able to hunt with it. Had it goose hunting today with Bismuth 1 1/8 oz. Gun is really something.
