I found this here: http://www.rcindia.org/fuel-and-engines/engines-engines-and-more-engines-!!!/?action=printpage
]Now this time it is some real vintage glow, and not one but two of them.
This time there's a pair of Gilbert, new and unused, but no box.
A bit of history about the engine from the current seller
Genuine AC Gilbert American Flyer .11 Thunderhead model airplane engine. Manufactured in the early 60's for the AC Gilbert company, these engines are all NEW OLD STOCK, not reproductions, or used. They were acquired from a hobby distribution warehouse that bought out the remaining inventory from the Gilbert company during their troubled last years, but they stopped selling them because the sat so long, the lubricant used in their manufacture got hard, and the labor to take apart and clean was more than the engines were worth, so they remained there until we rescued them. All motors have been torn apart, cleaned, lubricated and reassembled by us, and should make a fine running engine for anyone wanting an inexpensive yet powerful glow engine, or collectors of Gilbert stuff have been buying them for years from us to display in their showrooms. Comes with all the parts show in the picture, except the original unsealed Gilbert hanging card with instructions on back. I am now sold out on these cards, but all buyers will receive an JPEG scan that they can print for themselves, the Thunderhead .11 engine, original Gilbert fuel tank and hose, extra glowhead, universal glowhead wrench for both size motors, mufflers and screws (one short and one long as originally supplied by Gilbert to allow engine offset for control line operation), a spool of original control line thread, mounting screws, and one of the original Gilbert 7-3 pitch propellors. PLEASE NOTE, the propellor is supplied for collector display use only, for safety reasons, buyers are required to purchase a new 7-3 or 7-4 propellor if they intend to use the engine. As always, SAFETY FIRST!!!!!
And here are the first few pictures of the .11
It doesn't mention fuel though. I'd guess 30%^ is a bit too hot for it. Maybe 15% would be a good start.

That looks like a damn fine engine. Oddly it looks like the thing came as a box of pieces to be assembled.

http://masterairscrew.com/gfseriespropellers.aspx

The Master Airscrew GF series in my opinion is the best general purpose prop you can get. For $1.69 you get two to a pack. They do need balancing, and you have to cut down 6x3s if you want smaller ones for the 1/2A engines. I cut them down in 1/4" increments. For Tee Dees 5" to 5.5" work best, though 5.5" will bog in the turns a bit. And the Norvel .061 is happy up to 5.75" before it starts bogging in the turns, though it's at the low end of its happy RPM range.

AFAIK They came in a bubble wrap separately or in a RTF while in production. When AC Gilbert went belly up, some were ripped out of the RTF's and sold in plastic bags. I bought several of these from Polks. Some were bought from the factory as parts and these bags of parts were also available from Polk's. One of the bags of parts had an unfinished crankshaft. I will finish the crank if I ever need it.

Here are most of mine. All are .07's except the top one which is an .11. Got that one at a yard sale...without prop nut or thrust washer.

The plane would be great...but the "Automatic Co-Pilot" would REALLY prove useful !!!!!!!!!!
