Chic's first appearance as 'Chic Gaylord' 'holster maker' (he was a showbusiness agent prior; perhaps that's how he hooked up with Paris Theodore, whose wife was a showbiz person) -- I didn't bother looking throughout the country for Charles P. Gaylord Jr. -- was in 1953. His last appearance was in 1967, the exact point at which Seventrees took over his market. It was a pretty humble mention, too, of a his shop being 'somewhere' in NYC. He used at least four different street numbers on 45th St.
This image from the largest article suggests that he used a moulding press, if that's what is at his right and a bit further over perhaps a shallow pan of water:

The forum's upload system has made this image very small; but my version is large and the pistols on the bench are mostly High Standards, his known favorites. And not replicas at all, as stated in the caption.
