High prices for 'broken' or parts kit is pretty common, look up what KEH is asking for non functional Leicas this week.
Do the same with Hasselblad stuff, it's all too ridiculous, which is why I ask for broken/damaged stuff, here and elsewhere.
The Minolta Autocord (I have the '58 'export' model), is a very nice camera, with one weakness, the pot metal focus lever, and it's lense gives results as good a Rolliflex cameras, so I expect, high parts prices, go go along with quality cameras with no regard to the reality of a screw or spring.
