Technical Help identifying aftermarket frame

Can anyone help me identify this frame?
I'm nearly certain it's '33-34 Ford.

it's been boxed, has SBC engine mounts, a welded-in shock cross member, and a stock-style K-member.

there are six-sided holes punched in the K-member rails and driveshaft hole.

 

Here’s a scan of a fifty year old flyer for Mike Martens ‘32 frames. Martens fabricated his rails from three pieces welded together, and he started with Deuce frames but later branched out to include ‘33-‘34 frames. The x-member on your frame resembles his style.
