Help identifying an ABC prop 3.5

[MarkDanielsSr]

I cannot make this out even with magnifiers and glasses. Got the prop from a guy, set the Vision up with it on a modified motor. Runs and turns well, now as going to order a couple for duplicating backups, unknown numbers. Middle 4 digits could be 1515. I am not well versed in ABC. Can anyone help ? Cleaver look, 3/16 shaft on Lawless lower, motor higher than normal. I would also like to try on other mod motors. I can sharpen, balance, and modify. Thanks

Mark,
I checked several props and it looks like this on the layout of the writing. Hope this helps. I checked my 1515 and it looks simialar to yours. Mine is a 1515-19-38. Your could be a 1515-17-45 as it looks like it has more blade area than mine. Hopefully this helps you to understand what Jim's numbers mean. It is hard to see the number from your pics.
Mike

Mark,

Is it about 38 mm?
I would say it is a 1515-17*-45%
It needs a little more work on those trailing edges.
They run Very Well on a Modified 21Tunnel.
