Busch Pressman Model D screw lost

[Antony]

Dear members - I have a nice Busch Pressman Model D camera. I stupidly lost a small screw that is used to adjust the focusing mechanism linkage to the rangefinder. Would anyone have any idea on what screws the older USA made cameras used, or is there someone from whom I could purchase this from please? Thank you in advance.

First of all the screw is very likely to be an American thread size. 0-80, 1-72, 2-56, 3-48, or 4-40. I have found these in hardware stores that stock small screws or can order them on the internet.

To be sure of what screw you are talking about please post a photo of where the missing screw came from.

I just checked mine , it has 3-48x3/16 screws

I would definitely check my local hardware store, but if they didn’t have what I wanted I’d try McMaster Carr.

Screws, 3-48 Thread Size, 3/16" Length

Dear all - this is a pic of the missing adjusting screw - you can put a ball point pen tip in - that's about it. 245826

My Pressman has a screw plus a locknut to hold the setting.

[DMS206]

My Pressman has a top mounted rangefinder, so the size I gave earlier may not be the same as yours with the side mounted rangefinder

[Antony]

Hi rfesk - thanks for that - guess I need a locknut as well :)

Finally got around to checking mine, it's a 1-80 screw.

If you can't find them in hardware stores try hobby shops, there's a brand called Hob-Bits
they have 4 to 6 screws pre packaged and nuts of that size.

Jim C. Incredible - thank you so much.
