"very collectable" it is a salesmans display. i was collecting cameras in 1979. and it was not for sale. seen a few sinse then, just shows how the insides work AND were a total light leak. ihave a McKeowns' price book for 2002, ($80 t0 $120). pentax made an other one that did work with darker plastic that did work. i have never seen one of those - rarer. vinn
