Looks like a refinished 50s or earlier frame. Probably earlier, going on the low-down bend in the fork and the Osgear style rear dropouts, but having said that, my Hobbs has a low bend like that and it’s 1950. Canti studs were probably added later.
As bagpuss said, can you post some more pics of the lugs on the head tube and seat cluster? They look pretty distinct and It’ll be those that’ll probably identify the frame. It might be a matter of trawling the classic lightweights site until you spot a builder whose lugwork matches
Found a picture of the frame . See thread here on retrobike I have given a super bump.
It is Harry Rensch frame I can't see which model it is on the other thread .
