Very sad news indeed, he was a true craftsman.
I'm not a particular fan of engraved air guns, but have one of his earliest examples of an engraved 'Through the Blue' Webley Senior, fitted with standard grips. When I spoke to Don about this he vaguely remembered doing it, but most of his later examples were done 'In the Silver' and refinished after engraving.
Below are some photographs of said Senior. The grips were acquired later.
