I think all the "Liner bikes had twin top tubes , that kinda looks like Murray forks on an old Huffman.
Got any more detailed pictures? It looks like someone transfered most of the parts from a liner over.
Easiest way to ID most pre-'58 Murray frames is the unique collared frame tube connection @ the seat post, there are a few good pics of that detail in the post "Need help ID'ing this pre-war "Schwinn"..."
Stamp on the BB should have codes that tell the year, and whom it was built for. ~Adam
I believe the frame is most likely from the Murrey Fleet Line. The rat trap is probably off a spaceliner. The rear rack is definately a fleet Liner. The chain ring is a Westinghouse burner model. What a hodge podge. I just wanted it to build a shop themed bike and I love springers. Going to start tearing down
