Horseman 120 film back parts

[Katmandaddy]

What size thread are the screws that hold the front (back?) Camera side plate on a Horseman 6x9 film back. I'm building a 6x9, 65mm fixed focus camera and I'd like to use longer screws to attach the back to the wooden box I am building as the camera body.
Thanks for any help you can provide.

These are metric screws with a thread pitch of 0,4 mm. Size of the screws is - as far as I can evaluate from the image - 2 mm diameter and 10 mm length.

Go to an Ace hdw store & test some. But 2mm may be out of range for their stock. Another store is Hobbytown,
they stock screws for RC cars & all are metric.
