RE: OS .60FP
Yes, the sleeves in the auction are for the old ringed, cross-flow Max-H .60. See the bridges in the exhaust port.
Even if a .60FSR sleeve would fit (which I seriously doubt), you will need a complete ABN P/L set. If you could find one it would more than likely cost more than a complete used FP.60.
I'm not trying to discourage you. But, I've been restoring old OS's over the last year or so and parts are simply not easy to locate, and when you do find them the price is usually ridiculous.
