Just wondered if anyone has any history on these things, I've found several links online to a place, Cole's Power Models that provides castings for some Wall engines, although not this one I don't think. Information seems thin on the 'net.

These plans are from a old magazine, Science and Mechanics craft print #177. This is a water cooled inline 4, 7/8" bore 3/4" stroke OHV. They were my granddads prints. I also have a copy of an old catalog/pamphlet listing all the different engines available from Mr. Wall at that time. These are roughly 50 years old or more, I could not find an exact date (don't have the magazine) but this was in a time before zipcodes as we know them today. :P

The plans are fold out, 2 sheets roughly 24" x 36". Probably not the best design any more, but a neat peak into the history of model engineering perhaps.

Hello. I noticed the drawings you have for the Mighty-Mite. The drawings you have are from the 1954 Modelcraft Handbook. The engine is the E. A. Wall 30cc OHV 4cyl. Coles Power Models sells the casting kit for this engine. There catalog number for this engine is C602. I was wondering if you would like to sell your drawings or sell me copies, most copy stores have copiers this large for blue prints (Kinkos). You would be very well compensated for your efforts. I collect old prints like yours. I have built the engine in the prints only I used the E. A. Wall drawings from Coles. Thanks, Bob
