I was thinking the same thing before I read Gary's post. Zabiic doesn't look as bold as all the textured areas of the frame, it kinda looks out of place. it's a cool frame regardless!!Never heard of ZABIC. I also never saw a Milligan with that name printed on it. Probably the original owners name. I know that the Deerslayer and Killdeer slingshots were cast with ZAMAC, some kind of aluminum alloy. They were made by Tinker Manufacturing out of Lapeer Michigan. Hope this helps.
