That powerplus it the best one I've found and its very very good. But I realised I have a base that might suit the dark green catcher I have. It's close but not quite right.
This base itself is quite strange because of its dark colour, the black victa logo, the lug holes for a large cowl and it's supposed to have a remote primer. The base itself isn't painted, I haven't really paid any attention to it since I got it because I didn't have a catcher and thus no interest. But now I'm Interested in it. Again, it's not quite a match but it's close.
But the base has lug holes for a large cowl and a remote primer, so it's before the change to the cowl. I think it's a store brand Mustang but different cowl to the typical style. SPECULATION
