You'd get more for a complete camera , rather than selling it as a parts .
It might be worth your while finding a compatible part to make it compleat .
Regards price , for a specialist camera .
Depends on if you can find someone that wants it , and how much their willing to pay .
Heavy and uncommon doesn't mean expensive .
The trick is is to have two people wanting it , both bidding on it .
You could try it on eBay with a starting bid if the minimum your prepared to accept for it .
Have it on for a week , and renew the listing each time it doesn't sell .
After a few attempts , you might realise it's not going to sell for what you want , and you have to relist it at a lower starting bid .
Avoid listing it with a hidden reserve , there a big turn off .
You could try listing it at a set price too , or having a firm that sells cameras do it for you for a commission .
In the UK Ffordes do this .
You send it to them , they list it at a fair price .
If they sell it , they keep a percentage .
