Looks like a W2EWL special from an article in CQ, "Cheap and Easy Sideband".
I believe it was 75 and 20, phasing type. If you google "W2EWL special" you'll come up with some descriptions. Here's one link...

Some great nostalgia there...there was a ham in Pontiac whose mobile plans were a Commanche and a 2ewl special. He was a barber (and not a very good one), but it was always a great hamfest whenever it was haircut time. His stories of his hernia operation always had everyone in stitches (no pun intended). Not to mention the time I went out to his shop after a long absence and told him we had had a son. His reaction? He told me that I should called him up on "the night" and asked him, "Hey Keith...should I let 'er rip?"
He was W8BQG (Bald Queer Guy) He was bald, and queer didn't have today's connotation at that time. (Or maybe it did...his sense of humor was outta site.)
BTW...he ran an Eldico 100F & 75A4 at home...later a TR-3
