Even though these tubes sets aren't all confirmed Britte Freres sourced, I wanted to put them side by side in an attempt to jog my memory where I've seen the hammer stamp recently.





Siemens Martin Martele






Jno. Hy. Andrew & Co, LTD


V. Halska & Company from Littlegun's site.

Other than a marketing ploy, why would one want "Sheffield Steel" tubes instead of a local name steel type? Can you really imagine 500k tubes being held to one of those large grinding wheels each year? Tube makers were a hardy lot and in the gunmaking centers I think that a handful of certain families were sourced for tubes.



Kind Regards,
