Well, the yoke (rails) usually sell for $70 on ebay. A striped body goes for $50-$75. A good curtain on the rollers $40. There's $160-$195 before shipping if you need the parts or strip it and eventually sell them minus the listing time, packing and shipping time, and listing fees.But I know I can repair things, because I can fix anything. That's not really my question. My question is whether my $177 can still be considered a good buy.
You have failed to state exactly what is broken and it may be just misassembled. Then there is the overall appearance to be considered.
Generally a Speed body needing servicing and or minor repair goes for $100 to $150 depending on what is wrong.
The camera and leaf shutter in working condition with clean lens goes for around $350 and said freshly serviced around $500 unless you buy from the seller looking for the collector that has to have that one then you'll pay 2 to 3 times those figures.
you probably got a good buy but without seeing it or knowing what is broken it will be a SWAG to give a definite yes or no answer.
I'll fix it for you for $250 + shipping both ways or I'll lease you my 5# sledge hammer for $50 + shipping.
