Dunk, I have a Tech 70 which is 175####,with a 100 f/2.8 Linhof Technikon in a synchro-compur shutter. I purchased mine off of and old photographer, who used it to photograph Pope John`s visit to Australia in 1970. From memory he told me that he purchased it new in 1966 or `67, it came with its original passport and sales brochure. On the back is a print code 6603/11, which usually indicates the printing date = 3mth. 1966, also inside are some prices in Aust. dollars (we went decimal Feb 1966), Press 70=$1771 body,Super Rollex back 120=$362,Xenotar80mmf/2.8 $1230,Camera case= $469. Unfortunatly, I have only the one lens for mine, I hope this has been of some assistance to you, all the best Alan.
