It doesn't hurt to try but I doubt they will give you a partial refund. I had a similar case with a barnack from KEH. They will take it back if you choose but they won't take your word for it that the shutter is off. I ended up keeping the camera and getting it repaired. I've gotten great bargains from them over the years so I didn't really mind the bite on this one. I also brought a classic camera back to life and that is a good thing in itself.
