Numrich Gun Parts Corp and SARCO should be able to get anything you need for a Star B.
Back in 60's, 70's, and 80's Star pistols were reguared as cheap Spanish copies of Colt 1911's chambered in 9mm. IMO that's a very one sided look at things. They look like 1911's but there are quite a few differences. The Star B series pistols were desgined and built to military standards. They were at one time or the other issued side arms of the Spanish military and police.
I have a NIB Star B Super in 9mm Par and IMO it's a nicely machined and finished pistol. It's not worth much and probally never will be, so I don't have a clue why it's still NIB and unfired after all these years but I just don't ever shoot it. One of those deals where I bought it for nothing put it in my safe and forgot about it for a while... Maybe now I'm stuck on the it's not built anymore thing....
I also have a Star BM that I bought used (and abused). I've shot it quite a bit and even thou there is some wear and tear it is still more than capable if I do my part.
Bad thing is, by now most Stars are at least 20+yrs old. Many were imported here as Military and Police surplus -so already well used. Because they were low priced weapons even when new, they were lowly reguarded and treated like "truck guns".... To say never taken care of - would be an understatement considering some of the Stars I've seen. It's too bad IMO, when taken care of properly they are as capable as any weapon.
Good luck fixing up your Star.
