It's a laser etchable POM. I am undecided, but wanted to laser engrave the bottom of these to indicate a) that they are repros, and b) where they came from
Well, this took way too long but I'm finally set up much better to work on arcade projects. I machined samples today and need 3 US based members who are willing to test for form fit and function. Once the parts are confirmed the project should move very quickly.
These parts were "deburred" by hand. Final versions would likely be tumble finished.
