This database is currently under construction. I am adding serial numbers/pictures daily. Check back to see your engine, if I have a picture of it, or to see engines that interest you if they are not posted yet. Please do e-mail pics with serial number of any engines that you do not see listed. Thank you in advance for your assistance!
This Is A Database of Surviving Serial Numbers That I Have Witnessed.
These photos consist of all sizes of Associated built engines located all over the world. Any photo that I have personally taken at shows, sales and auctions as well as those e-mailed to me by engine owners and a few found posted on the internet. As always, ownership is anonymous and if any picture is requested to be removed, I will gladly do so. I will also be happy to update any picture with a better shot if any one desires to e-mail/snail mail me such a picture. E-mail photos to ksmigle @ hotmail.com (Remove Spaces) I would also appreciate any corrections!
The one thing I want to accomplish by posting these pics of various engines according to serial number is so that you can study various changes to design and style. VERY little documentation exists so the best way to document how these engines evolved is to see the engines themselves.
Please, send me your engine pictures with serial numbers listed so I can add them to this listing. This is a very important process of historical verification. I hope these pictures can be used as a great reference tool.
Make note that some Iowa Oversize engines of 4HP & larger seem to have an "A" designation at the end of the serial number. I have included this letter "A" in the listing of these engines that I have pictured. If I have listed more than one photo of a non-Iowa Oversize engine, I have given it a small "a" designation. Do not confuse a serial number with a small "a" at the end as being an Iowa Oversize engine.
These serial numbers do not fit into any system of numbering. The only thing consistent about these engines is that they are all very early engines. I will only guess and say that they were numbered before a system of numbering was devised.
