Sniper mount steel question

[Roger Payne]

My late machinist Graham Smith made about thirty of the bases for the TP rifle around 25 years ago, or maybe a little more. He also produced three sets of rings. But then he was a savant, & he died in 2005, taking his machining secrets to the grave with him, the mounts all selling quickly, at the time. Graham made them as the late Pete Bloom turned up thirty TP scopes complete with rings from a European dealer - I think they were scopes from rifles that had ended up in either Belgium or Holland. I heard the authorities destroyed the rifles but released the scopes. Pete sold at least some of the scopes/rings & repro bases on 'that' internet auction site.
