It’s a Westfield.
Something to do with the East/West distribution.
I was actually hoping for a Murray, because those frames got the curved seat tube.
But, through pure chance, all of my Elgins are Westfield built bikes, so I figured, why change now?

To the best of my knowledge, Murray built both curved and straight seat mast frames. The Westfield frames don’t have the electro forged sections like I see at the top of the seat stays in your photos. Maybe @Krakatoa or @mrg can set me straight.
