This one looks like a pretty basic design that was popular back then, but the issue is the front end: It's not cut with enough clearance for the front arms. Neither the classic narrow or newer wide arms fit correctly so I don't know what this was designed to use. I'm sure doing some surgery on it is possible but I'd rather not have to.
