What kind of frames are these?

Anyone have an idea as to what vehicle either one of these frames were from? I know, it's not much to go on, but that is all I have to show. I am posting for someone else.

Might be teens Buick. I have something very similar in storage like that. Don't have a photo of it and won't be up there where it is stored for a few days unfortunately. The Buicks of that era had a chassis number on a small oval piece of aluminium riveted to the front of the left side rail.

I Think the frame can be as new as 1923,it have had "cantilever springs",and the last 1 yard of the rear frame are missing what I can see.

It does not look like the Buick frame that I have in storage. Mine is a 16-18 small 4 cylinder frame.

Mine is an early 1916 six cylinder one. The only thing that is hard to pick from the pics here is the depth of the side rail. The 1916 chassis is, at a guess, about 8" deep.

Here are a 1923 Buick 6 cyl.frame,dont know if it`s a 40 or 50 series.
