I have an order for (400) Amiga 3000 case screws (color matched, with the nylon washer) on the way to me from the manufacturer that made these for Commodore back in the day. They should arrive by April 23, 2021. They are not cheap, hardware store variety screws, but, are rather expensive fasteners that the manufacturer currently sells to the military and such. A set of 4 is going to cost you $6, plus shipping, which is my exact cost.
If you are a member at A1k.org in Germany, I have the sale posted there, along with the link to the order form. As it stands, more than half are spoken for in a day and a half, with a limit of two sets of 4 per user, at this time (guess where all the A3000s in the world are hiding?). I have no doubt I'd be at zero left if I had let some of the folks there who wanted 10 sets each order that many. A1K doesn't allow the sharing of links to their forum for things like this, if I remember right, hence my not posting the direct link.
I do not want to keep track of users from different forums, so unfortunately, for the time being, I'll only be taking orders from users who have an account on A1K.
