I think Pugwash would be the go. Otherwise I will find out the name of the fellow that works for Mr Friedkin and handles the Jeffery records AFAIK. Have his name somewhere!

One or two of the Hollands I have bought came with the e factory record. H&H are good to deal with, I think it is GBP30 last time I ordered one, a couple of years ago. They were also good when giving me details of the extra 375 Flanged Mag barrels they built for my 500/450. Although extra work is not well recorded in their system.

Cheers, Chris
