I am pretty unfamiliar with the V-series so I am leery of getting it. Does it look like just a CLA jobbie... or one
for the scrap heap?

I wouldn't touch it....even assuming that it is in good shape, it will need a lot of parts before can take a picture. Missing "screen" a used Acute-Matte D screen $250 used, 80mm lens $600 used, film back $200-250, view finder $75 for a WLF to $1000 for a metered prism....winder electric ~$400, crank ~$75. A 503CW body in ex condition with screen, crank, WLF finder and caps will run about $900-1000. A better value would be a late 500 C/M in ex condition. KEH.com is a good place to get an idea about what is available on the used market. Just remember, Hasselblads aren't cheap to repair.
