Re: "Lee Speed was chambered in, and I quote, "7x57, .303, 8x51R, 32-40 Winchester or .375 Flanged Nitro Express (2 1/2").

Why is this incorrect? Looking at a number of the B.S.A.Co. catalogues, I find the above to be correct, as long as you include the rim measurement in the 500/320 Flanged N.E. (ie 8x50R Austrian Mannlicher) and the fact the 32-40 Winchester was chambered only in the single-shot version.

Apparently, although I have not yet received the old catalogue promised from overseas, Alex. Martin chambered B.S.A.Co. C.L.L.M. (Charger Loading Lee Metford) actions for the .256 Swift Flanged, as did Fraser, for the .256 Fraser Flanged; both of which are simply the British names, along with .256 Mannlicher, for the 6.5x53R Dutch and/or Roumanian cartridge.

Quite likely, as has already been stated, the rumours about the Lee Speed actioned rifles being chambered for the .405 Winchester are the same as the ones about them being chambered for the .35 W.C.F. They both relate to the Remington-Lee rifles, which was chambered for both of those cartridges.
