I sincerely doubt that you will find any. These are as rare as chicken lips. I went through this when I was making my first try at running ST.60's, as these were sup[posed to be THE prop for that engine. I found one or two here and there, but kept trying others. This was on a 72 ounce Cardinal. I pretty much tried every off the shelf wood 13-6, and got to a point where the Brodak 13-6 was the best of what was available then ( about 10 or 12 years ago.) Then I heard about Vess props and got a few of them to try. I put up two flights one Saturday morning with the Brodak props just for a base line to get RPM and fuel load noted, then put on a Vess 13-6. Right from the instant it started I could tell it was better just from the sound. My helper that day was pretty experienced with ST.60's at that point and his eyes got big and round also! I had to open the needle just a bit to get down to the same RPm, and then he launched. The model was much better for what it was, a 72 ounce oinker! But I felt if I had to I could enter a contests with it. I got to the overheads and I could hear it act like it was running out of fuel and upon pulling out it quit a half lap later and I had the same fuel load as for the Brodak prop. Fast forward to the last year or two, I acquired one of Sparky's cast off St.60 ships, only much lighter at 60 ounces or so. I installed the same engine in this model and started testing props again with pretty much the same results. this time around, I added Xoar 13-5 and 13-6 to the mix, and I think they are the best you can do for an off the shelf, reasonably priced wood prop. I think they work better than the Rev-Ups in my limited experience with them. I haven't tried to get any Vess props lately and I think you can only get them direct now, but they are a very close second. I'm not real fond of the scimitar shape and blue trim colors they have on them but that's not why I tried them! They did work very well and I would give them the edge over the Rev-Ups. The Xoar is probably easier to find also. Good luck with whatever you find and I would suggest experimenting a bit with the newer stuff.
Type at you later,
