Apologies for the delay in responding .... the screw press had a counterweight ball so 'throwing' the arm into reverse took little effort, then hold the arm while positioning the next piece for stamping, and then let the weight of the ball screw the die down to stamp the oil pourer body. I suppose the die stamp is still on a shelf at CESCO: it was not the D^D but just the broad arrow mark that was specified. I've no idea of the legalities of it all. There was a specification as part of the contract and I think my father had a die maker make the stamp once the contract was won the first time (back in the 60s). It was applicable to several of the contract items the company made for Defence over the years: oil pourers, meat safes, square 'outboard motor' funnels (this last one having a set of drawings dating from the 1930s!) and so on.
