WTB UF-1405 brass or copper pill. Do they exist?

I am looking to build one of these and was hoping I could get a brass or copper pill. Do they exist? If so, any idea where to find one?

Thanks Matt

I’m also search them in brass ,who have a pairs I would buy it

I don’t know off the top of my head, but did you try kiriba-ru?

EDIT: Just checked his thread and there was this post a while back. In it he said he could make those, but wouldn’t if there wasn’t any interest. You should PM him.
