Marrakai:

I think you've gotten a bit confused on this one. This rifle is a Rodda and was built in Birmingham, not London, between 1904 and 1925. I think you probably meant Joseph Asbury, a Birmingham barrel maker and barrel filer (formerly an action maker) who was active in this period and is known to have used "J.A" as his signature. He was in Lench Street during this period, while Rodda was in Whittall Street. He is almost certainly our man.

The rifles in the string mentioned are those of Asprey Plc, London. Asprey's is an old firm, started as a calico printer, that became known for accessories. In late years, they became famous as jewelers and flateware makers. They didn't enter the firearms business until 1983, and did not become gunamkers until 1989. There were no Aspreys previously listed in the Birmingham, or London, gun trades.
