Handles for 1930's wolverine faucet stem

[Sepharad]

fisrt, thank you all. Because of your 2014 posts here, I was able to identify my stem. I obtained 2 stems, but cannot find handles. The broach diameter is 7/16. The splines are another issue. I have read there are 15 points on a wolverine broach, but I count 17. Where can I possibly find a set of handles? Will American standard 7/16 22 point fit? I don't want cheap looking handles with set screws. As far as I can tell the originals looked like American standard cross handles.
