the clink when you hit it sounds like ABS - today's ABS gets brittle just like that if you heat age it (the butadiene is the rubbery part and subject to attack). I'm sure it was injection molded , that's what ABS is good at. If you are going to try to cast it, you may want to go with acrylic - easier to use and more UV stable when you are done. ABS has poor chemical resistance to most hydrocarbons - stress crazes easily.

Jerry from Yesteday's Radio drops in here - maybe he wants to look at adding it to his "to do list"?
