1923 OTCA Coaming Screws?

[Graves]

The 1923 OTCA am I currently restoring came to me with aluminum coamings already removed and without the screws. Can anyone tell me what type, size, material screw I should be using to mount the new coamings? If the photos show the original screws they look to be #4 or #6, slotted, rounded head screws made of brass? Thank you.

Putting this thing back together as we prepare to move. It's still short one coat each of varnish and paint. New can of paint coming from Kirby along with a flow or conditioner product George thinks will help the bubbling.

I annealed the old stem bands carefully with an acetylene torch, since they were age- and work-hardened and I didn't want to crack them. Annealing revealed two places where cracks were starting next to screw holes - you could watch the dull orange heat travel across one side of the hole and not the other. Did not attempt any repair although I suppose I could have tried...

This forum post suggests 7/8" #6 oval head brass screws for a '51 OTCA. Which seems to look a lot like what is used on all the '20s OTCAs I've seen pictures of here.
