I've already played with the safety button and I think I've filed enough off.
I'm going to stay with the factory Ruger tube for now just because it is cheap and I've already spent too much on this project due to the scammer.

Mr Glenn Fewless should be returning my 450BPE Alex Henry falling block soon also and I suspect that he'll want to be paid for his superb efforts in overhauing that beater. The progress pictures have made my mouth water. It's off to be color cased now before final assembly. All origional marking have been restored during the work.
Douglas Mann has restored the wood and Mr Fewless worked magic on the metal.
I'll do a 'show and tell' when it arrives.
