Afterthought: I believe the postwar transitional .22/32 revolvers would have an ejector star you could use. I'm not sure if the cylinder assembly dimensions of the Model of 1953 Kit Gun stayed the same, but you might be able to use a star from one of those. I don't know but am assuming that the ejector rod threads on the Model of 1953 (Pre 34 or Pre 35) were the standard right-hand threads until 1960 or 1961, which is when they changed for the K and N frames. So you might be able to find a star from an early Model of 1953 and press it into service.
There is a heavy conjecture component to this post, so it's grain-of-salt time.
