Hi Jack,

Welcome to the group!

If there is no BRI number on the frame up front, it's not one of the 104 cars that were built in the Butler jigs. It's most likely an Arntz but still could have been built at least partially by Butler. As you've probably read in past posts, Butler built 60 frames for Arntz, some of which received a small number stamped up front. A few of these frames were sold on by Butler after Arntz went under.

Outside of the 104 Butler cars (or a history from all the previous owners), it'll be hard to tell exactly where your frame fits in. I can get pretty close though with pictures of the frame, especially the outriggers, crossmember and suspensions mounts. So post them up and let's see what you've got!
