[Leica] Leica IIIc film loading question

[alaxsxaq at gmail.com (Glenn Stauffer)]

Ran a roll of B&W through my IIIc to check that the shutter was
working OK and noticed a few things wrong with the way the film fed
through the camera.  The frames run together and the image extends up
against and slightly into the sprockets on the frame number side.  Not
consistently either.

Does this sound like I wasn't careful to ensure that the sprockets
were engaged when I loaded the camera?

I'm thinking I ought to send it off for a CLA sometime.  There is
someone in the Carolinas or Virginia who does a good job with screw
mount Leica's, isn't there?
