The Hobby shop I stop at on my 2 day run is pretty much R/C Helo's and planes, I am the only C/L customer. The owner was contacted by a elderly woman whose husband has recently passed away concerning his old C/L planes. When I stopped by yesterday he showed me what was there. Most of the planes are pretty rough in shape, but there was over a dozen engines all old. Diesels, about 5 of them the 2 I looked at had ED on the case. One was about a 20ish size the other was smaller than an 049, looking it up in an old AHC cat. it's probobly an 027.

There where several K&B greenheads a 29 and 35, the exhaust was shaped like the O&R's.
About 4 O&R's one was a 29 for sure one also had a blue head ??

1 Fox 29 with the exhaust rectangular with squared corners not rounded.

one large Spark Ignition set up  still in the remains of the nose section of a plane.
It had Super 60 on one side and CUB on the other with a patent number.

There was a DeMeco Speed Wagon 30 in restoreable shape with a McCoy 29 rear intake Red Head (I've never seen before) was a little tricky getting out but managed to without destroying anything.

I'm thinking of making an offer for the whole batch but don't have a clue what to offer. I know without pics of everything and a list of all the engines this isn't much to go on.

Any info on the engines and maybe some price guesses would be helpfull.  Thanks
I will get a complete list and pics when I go back next friday.

I'd start by searching Ebay, check the option to search the completed auctions and see what they're going for there.  A lot of the same engines that go through MECA go through ebay for less money.  Depending on condition the price can vary a lot.  Just about any mostly complete 29-40 size engine will bring $40-50, maybe more if its nice, really nice engines can go out of sight.  The Super 60's have been bringing $100 or more for complete engines on Ebay lately.  O&R's are common but they seldom drop below $40 and sometimes bring stupid prices.
