Radiator mystery - not '38

[jeff]

Some years ago I pulled a radiator out of a '38 Special parts car. I started to clean it up, pressure test it, etc. when I noticed it is not the same as the one in my '38. (although it certainly was installed in the parts car) The filler neck is not offset like my '38 is. Part number is: 3114744, with 48G also on the tab. (1948??) Anyway, I fixed a leak in the top tank, repaired the rusty section of frame at the bottom, pressure tested to 5 psi, and painted it. Now to find a home for it - any ideas of what it fits?
