So, I've long wanted to put together a couple three spring cars, one a lakes modified ala Art Gerrick or Bob Giovanine, and the other a Legion Ascot Class B type big car. As such, I've gathered up some parts for these future builds. I had narrowed and shortened a 20s Chrysler frame for the lakes car, and had sourced a perfect Essex frame for the big car. However, when a pair of old chrome Essex frame rails popped up for sale recently, I decided those would make an even better platform upon which to build. Problem was, they were way up in Minnesota, far from Pennsylvania, and I really didn't want to make that drive, despite the good price. I got lucky and was able to find transport for them, so I bought them. It took a few weeks to get them in my hands, but as soon as I did, I knew immediately they were not Essex rails. What they are is even better. What they are, as I'm sure most of you were able to deduce from the thread title, is a pair of old chrome three spring big car frame rails. They appear to be nicely built as well, showing excellent craftsmanship. They've not been modified and have only one old weld repair on the inside of the right rail near the front spring rear hanger. Based on witness marks and discoloration where the shocks, spring mounts etc were bolted, it was an assembled car at some point, so it's possible that it was a restored/museum car that got pulled apart to use the engine in the restoration of a better known car or something similar. I'm hoping that someone will recognize them one way or another. The frame shape, both at the front and rear, as well as the location of bolt holes will be what will identify it if its identity is to be found. From studying pictures I've noticed some similarities to some restored cars, which might indicate the same frame builder, but nothing close to definitive. Thanks in advance for any insight, suggestions, information, etc.
