what are those steel spring strips for?

<p>Greetings.</p>

<p>Just received a 220 back for my Rb67 ProS. However, upon close examination I noticed that of the two steel springy strips, that make a see-saw in the middle of the back, one is missing the steel pin.</p>

<p>Here is an image I found on the net that shows them:<br>

<p>So, I have one of the roller pins at the end of the see-saw missing. Seems like either it was pulled out by mistake or somebody removed it. Is this back still usable? Would that pin-less spring scratch of damage my film?</p>

<p>Thanks.</p>

<p>That roller pin at the edge of the chromed bracket supplies tension to the roll of film. Will it scratch the film, maybe, tending to yes, plus the film might loosen up on the roll.</p>

<p>Paul, thanks for the link. I think I am going to lurk there in search of some additional lenses for my RB67 ProS :)</p>
