Barn Find of the Century.  I think it would make a great garden planter.  It already has rocks in the bottom for good drainage  ;D

If the bottom end is okay, it would make a good candidate for an 836 kit.

 I heated it in the gas grill and slid the sleeves out, it's now a nice naked cylinder with good fins. I'd love to sleeve it to 72mm, get a set of pistons and re-assemble my buddy's old stroker motor.

Did you leave the pistons and rods in the sleeves?

Yes, I spent way too much trying to save sleeves and pistons that were junk. The sleeves might have been OK with a 4mm bore but I wanted an early cylinder for big sleeves anyway.
