Looking to identify these K-Planes. There is a number cast into the main body number 24 103535. Dimensions: 20" L x 14: w x 10" h

Looking for age and parts availability. I'm wondering if it is worth it to pick these up on the cheap?

It's a old pair of 280, it has the old style hydrulic cylinder.

like Harvey those are the old 280. The new style cylinders are $305.00 each and thats the only thing you would have to change

If I bought these for 300.00 is it worth the money to replace the cylinders and clean them up or should I just buy new. Also will all the newer 280 hardware fit these? Was the skag added later to these or did they come with it? Thanks again.

the breach in the aft rib concerns me. With enough pressure the plane could break.

Bought new 280's this spring. Save yourself alot of time and grief and purchase new. After hunting down used pumps/ cylinders/ hardware and not knowing, if the chit even works, your way ahead of the game.

Buy new (or newer). Those are early 1980s vintage, before sacrificial anodes were standard -- and they're modified, to boot. Don't take the chance, man.
