IIIf RD wind knob loose

[Mike Kovacs]

I have this "new" IIIf RD that came day (my first real LTM yay) with a problem. The knurled part of the knob rotates separately from the top. You can see the ASA numbers spinning around in there when it rotates.

I think there is a set screw "15-10.29-18" in the service manual recently posted, simply described as "Schraube" (screw) that is missing. I recall that when you remove the knob, you are supposed to turn this set screw a couple of turns, then CCW on the knob to screw it off. There appears to be no screw in the hole (shining a light inside to see it) and I don't see how I can unscrew the wind knob without it being in there.

Any idea where I can find one? Service manual is too hard to see but is it a special shape? If its standard, what thread size and dimensions?

Damn, the LTM Sonnar T 50/2 looks good on there

I'm sure Dan Goldberg (http://www.dagcamera.com) can sell you one.

Thanks Don Goldberg does have them. (but I found mine on the floor under my chair!)

Moral - open cameras coming from the mail somewhere you can find all the parts rattled loose in transit....
