You might try asking on the "Classic and Single Barrel Rifle" forum of www.doublegunshop.com/BBS when you get everything you can from the 'Fire. I think it is the fourth forum in the BBS list; may have the title slightly wrong. Lots of classic bolt and single shot collectors and 'smiths there, plus lots of Anglophiles and a flew Anglos. Very civilized crowd in my experience.
