Standard joke in this house, if you don't know what it is you call it a Dodge part. Dodges had either cast or forged posts that fastened down though holes in top of the cowl with the ends of the posts being about six inches long and having threaded ends.
The curved bottom of the lower piece and the stanchions that fasten to stub posts are two distinguishing features of that setup. Not all that many cars in that time frame had the glass cut to fit the cowl and most were straight across the bottom. Very few open cars in that time frame had that style of corner on the lower frame as most were rounded on the ones that curved to fit the dash.
Those bolt-on stanchions look a whole lot like real early stuff - I'm thinking circa early teens. Not sure make, as it could've gone flat, too, using a cowl-filler piece. I'm also thinking non-mainstream car-make here, but it'd be one that was more-or-less "assembled". This'll get interesting to figure out just where these came from. Marcus...
Yes @VANDENPLAS , it's a Dodge. Now take this pill like the nice Doctor ordered, so you can relax and sleep. That's a good boy...
Looks a lot like the frame and stanchions I picked up at a swap meet a few years back. My guess is Chevy. Not that it matters. If it fits, that'ts the what it's for. Hotrodder's mantra.
Boy.. hard to say! Obviously from early 20s open car. Yes..I agree, if it fits, that’s what it’s for!!
