No idea who built it, looks like it utilizes a '39 Chrysler hood and grille upper section, and looks like late 40's-early 50's Studebaker rear quarters and trunklid, severely narrowed, maybe motorcycle fenders? I don't love the proportions of it, but the execution of the build looks pretty good for the time at least.
Thanks @anthony myrick...as @Squablow said an odd vintage duck well executed and likely a homebuilt based on the Mechanix Illustrated how to series way back...I wouldn't be surprised if this was a survivor that was resurrected in the late 60s, early 70s, maybe even the 80s by the vehicle in the background...these certainly carried numerous levels of fit and finish with many options for improvising varied parts available in the wrecking yards of the period applicable to the build... It appears the Ole Mechanix Ill. Series really did get the creative juices flowing back in the day as there have been many shared here over the years based on a mid 30s Ford Chassis as a base...
that car or one similar was a magazine plan … back many decades ago. maybe popular science and mechanics illustrated ? edit… i didn’t read beyond the OP before posting… i’ll go back to watching sesame street now…
It should be posted in this thread as it's all about these homebuilts via Mechanix Illustrated... https://www.jalopyjournal.com/forum/threads/very-ugly-but-kind-of-cool.1100048/ Again give the plans to 20 builders and you'll get 20 versions with some pretty well done...
