[Frameworks] sprocket dilemma

Hello mo,
   This is definitely not too much information and is very helpful. I actually
found the photographs on ebay-- someone is selling this same exact camera for
500 hundred dollars! I am not trying to sell this though, I just want to use
(I wonder why they are selling it for so much..)

The big questions at this point:
1. is it a double pull down claw?

- You came to the conclusion that it is not a double pull down claw, which
after looking through and running film through the camera I think is true.

2. can you see how the sprocket wheels can be removed, and then re-

-I don't think that the camera allows one to remove the set of sprockets so it
would have to be done by force.

Have you ever used a double sprocket camera without removing the extra
sprockets? If so, was the image effected very much by the irritation of the
extra sprockets?

I am located in New York at the moment but I am from Los Angeles and go to
school in Amherst, MA. Well I've got to say-- thank you very much for all of
your help so far, I really appreciate it.
