Don't just thread lock it and ride it. Figure it out for the sake of your teeth.
I will caveat the rest of this by saying that I'm unaware of archaic niche BB standards and an assuming the frame ought to be BSA threaded.
Measure the width of the shell, i.e. from one circular face to the other. Unless there's an ancient British track standard I don't know about, you're hoping for 68mm. If it's less than this then check the frame BB circular faces. Have they been attacked? Are they actually in suspiciously tidy, crisp condition suggesting they have been over-faced?
If you've got calipers then measure the ID of the frame BB threads. You're hoping for 33.6-33.9 mm.
Look at the frame BB threads. Have you double checked that you've got one left-handed thread (drive side) and one right-handed thread (NDS)?

I’ve got an old British track frame and having a weird issue with the bb, the threads in the shell are all clean and tidy, however when I put in a bb it seems to be loose (ie it moves in the shell) also when I put in the left hand side it’s pushing out the right!? I’ve tried a few different bbs and it’s the same each time.
Is the shell knackered/worn and if so is it worth retapping it to Italian threading, or should I risk my life using thread lock and crossed fingers???
