...It seems strange that FN would refer to the chopper lump system as a demi-block...perhaps it is both...
Robert, I would like to hear your thoughts on the definition of "Demi-Block". I have read that it was simply another term for the chopper-lump, also that it applied to the "Dovetail Chopper-Lump". I also recall seeing a picture of an older set of bbls marked Demi-block which appeared to have a joint much like a Mono-Block. I believe they were of either Pieper or Bayard "brand". This tended to cause me to wonder if the original meaning was a block built seperate from the tubes but of two pieces joined together, rather than from a single block, as in the "Mono". Then again maybe none of these are correct. Thanks for any input you may have on this.
