finished all the measuring and modelling of the Bally hooded target based off a new skateball target, this is cheaper already made but will put it up at Shapeways in case someone wants a a custom colour or non pattern stamped.
interestingly the anchor point (hole) and body section around it, shaft up to the spring locations is basically a replica though the spring anchor point is beefed up on the bally version. The hooded section of the target is slightly lower at the top as is the base is slightly longer where it triggers on the drop down switch on the bally one.
so there are some similarities and probably came out of the same manufacturer with molds copied and adjusted.
LHS - Stern
RHS - 80's Bally
