So the shutter on my FM2n, kinda just.... shuttered.... One of the blades got jammed out of place, so now I'm thinking to get one of those non-working unit selling for parts from Ebay, and then give it to my local camera repair men to swap the shutter out. But I can't find the exactly model at the good price, instead came across a few FE and FMs for cheap. My question is while I know they have the titanium shutter, FM2N has the aluminium ones, I just wanna know if they will fit. I can't care less about the material, just wanna make my cam work again. Input please!
