Could it be a Viking? Classic Lightweights mention Vikings being stamped there with prefix letters on pre 1961 models.
I've got a 1952/3 Viking track/path that has got V and a number stamped in the same place. I cannot see well from the picture but I think the fork crown on mine is very similar if not the same as yours, though the head lugs are different.
There are some other frame number examples on here that could well put yours as a Viking. http://classicvikingcycles.com/frame-number-register/
