Sorry your email bounced...I'll clean out my mailbox and let you know so that you can re-send the photos...I will save your photos for anyone else seeking the same data in the future, if that's alright with you?...There's a new email on it's way to you with 5 pics of the chopperlump system plus 4 other pages...It seems strange that FN would refer to the chopper lump system as a demi-block...perhaps it is both...please do not re-send your pics until I send you the next 5 jpegs...were the first pictures the info you've been lookin' for?
