If the gold crown pocket castings are the same on a 4 1/2x 9 as a snooker table I have some corner castings if you want them, they are for a GC1 and have the ash try's in two of the corners. They need some help, but you might be able to do something with them, just took them off my table couple weeks back.
Let me know if you got any questions.
