Wait!
Before you do that, if you look, there's a little lever with a small spring wire going through it (you can see it on
this pic bottom center.) Checking it against my working KX (which has the same shutter arrangement), the little lever with the wire should be
lower and behind the end of the large L-shaped lever, instead of in front of it as it is here. Try getting it to the correct position before shipping it off to Eric (well, it'd be a good idea to anyway, seeing as he'll make it like new
)
