I don't think they sent many to the U.S. market but three models were widely sold here in the U.K. The lowest price boxlock was the non-ejector 'Yeoman' model then the Number 3 which was a non-ejector then the Number 4 which was identical to the 3 but an ejector model. My guess is either a 3 or a 4 by the looks of it. Lagopus.....
