Is the mark on both tubes? Are their any other odd marks? Info on Hungarian proofmarks from Budapest is sketchy after 1971 but I know there were some major changes in 2004, something to the effect that every 5 years a gun owning citizen has to submit there arms for reproof at their own expense. But I'm not sure of the exact current stamp for provisional proof. After the mid to late 1800s, tube production really fell off around London and in Birmingham say after WWI. I would say Westley sourced the tubes from Hungary, FEG mabye, and the mark is the horns of the red stag from Hungary. If the "T" were a "I", I would be sure of it, but then again the new mark may be a "T" for temporary or a hammer.

How do you fancy the 6mm Musgrave?

Kind Regards,
