Neither of these frames are factory WZ frame but standard Schwinn frames with aftermarket modifications ( belt dimples, brake & motor mounts ) so hard to put a value on as a lot of people did those mods, Cal specials were made around here in the 80-90's out of stock frames to supply the local whizzer craze ( whizz-in days ) as said the belt dimples on both of those frames are not factory, not sure why some of the whizzer guys haven't jumped in here?, Sorry I'm not trying to come off snarky either and sorry your thread got a little hijacked, green frame has some odd mods on the upper fender fender bridge and the frame is even more distorted on the other side of the home/shop done belt dimpling.
