Hi

Does anyone happen to know what size bolts are used to hold the Spring/Graphic back onto a Anniversary Speed Graphic please?

They're obviously not metric, I'm guessing they are some sort of American size/thread?

I don't need the length (that's easy!) - I'm going to buy longer ones anyway as I want to design some system that will take the Polaroid 405 back.

Thanks in advance,

James

its a 4-40 right hand thread.

You're in luck, then. That's a standard size that you should be able to find in a hardware store (I think you call them something else in the UK, but I can't recall). Failing that, if you have a model railway shop near you, they might have it in stock, although that size is getting a bit large for model work.

OTOH, if the UK has gone entirely metric in everything, you may be out of luck.
