New OPS .60 Super Piston and Cylinder Assembly #OP7371 New Old Stock

Description

This is an OPS New Old Stock ABC Cylinder & Piston Set for an OPS .60 Super piped RCA Airplane Engine in good condition. Please see photos for details. I acquired this in a box lot of RC Airplane engines and accessories at a sale which was full of high-end Speed and Pattern engines and parts. I am not familiar with the OPS line of RC engines except through doing research to list and sell these parts. I have two of these, one that is pictured and the other in its original packaging which is undisturbed. I am a bit nervous about selling the one that is still packaged without opening it to see its condition, but if you want to purchase that one undisturbed simply contact me after the purchase. I am also planning to list new old stock connecting rods and wrist pins for this engine shortly, a few other OPS parts including a venturi/needle valve assembly and a couple other OPS piston/sleeve sets for other engines. Feel free to contact me if you have an interest in such things before they are posted.
Here are the dimensions of these parts as measured by me (so roughly):
Piston: 23.85 mm bore; 22.65 mm high; 10 g weight.
Sleeve: 27.91 mm outside diameter at the base; 38.86 mm high; 48 g weight.
Please feel free to contact me if you have any questions or need additional photos. Also, I am happy to receive offers since pricing these things is difficult and I want to be fair.
Thanks!
