I guess it is a home breed engine...made of a Babe Bee, original No 2 stepped wall cylinder is swapped to a No 1 Black Widow thick wall/2 bypass design, tank is changed to a 8ccm extended volume one...Otherwise I do not see it too special.

I have seen a picture of a NIB (the plastic bubble with the spider) Black Widow without the black anodizing. This engine is essentially a BW without anodizing Huh...

A bit expensive maybe unless there is some kind of reliable proof and documentation of the Dale Kirn connection. Without the shipping cost, however, I just might buy this one for the pristine metal backplate but then again I am a bit silly about these Smile

EDIT: Whoa, hold the wedding! Am I seeing a late model Estes crankcase? No groove for the starter spring on the base of the cylinder Huh... Homemade it seems... Could bee a late model product engine with a stunt tank kit.

I see absolutely no Kirn Kraft bits on that thing. Unless the cylinder is a KK, but really hard to tell from a photo.

I noticed this engine has only 1 bid to date with only 3 days left. The fact there are no more bids might be a tipoff to its genuineness being doubtful from Dale Kirn. Description states, "Dual Bypass". Article in:

Wikipedia: Cox model engine

Refers to the pre-1996 Medallion and Black Widow .049 cylinder having 2 dual bypasses but no boost ports. Thin walled and no wrenching flats at cylinder top, my guess it is probably an earlier Medallion cylinder, may be 1960's to early 1970's. As KariFS points out, crankcase appears to be a later one. May be it's an Estes brewed engine? Someone intimate with years ought to be able to nail it down further.

If there are no more bidders, then it might make for a nice runner to first bidder.

Here is something of interest. I found a photo of what looks like this engine in:

Facebook: Cox Model Engine Owners, Ramin Foghani's Post 20 Dec 2016

It looks like I may have stumbled onto what this engine might really be, a Cox production engine for an earlier model Cox Sportavia RTF.
