Prewar Streamline frame ID?

[streetrod]

I just picked this 26" wheel frame up, the seller thinks it's an Iver Johnson but it's only got 2 head badge holes not three like the Ivers had. Any help is greatly appreciated! Thanks

The rear dropouts are fully welded unlike some I've seen that are crimped

The head tube is also one of the smallest I've seen, it measures 3.5".

It looks like a 24" bike frame. Measure the seat tube from the BB center to the top of the seat post. A 26" frame should measure 18". A 24" bike should be around 16". Gary

The seat tube is 18" from the center of the BB to the top. I also thought it might be a 24" frame so I stuck a 26" wheel with and aired up tire in the back and there's plenty of room, so I know it's a 26". I've been looking all over and still haven't found a frame exactly like it though...

Looks like a Colson, though a very small one! I have a 37 lwb (blue) frame, and a 39 swb (rusty). The year is stamped on the BB, apart from the serial #. The 37 is stamped 'F 7", the 39, 'K 9' -Adam

I was going to guess Colson because of the chain adjusters. cool rig whatever it is.
