Hi Bought this tank £5 (35+)years ago. Advise on pet cock size. I'd like to get the taps and make sure they fit before I rattle can paint it.
Links appreciated...........

Thanks, I'll order 2 x 1/4 BSP thread. If they don't fit I'll just keep them for 35 yrs (if I'm still here) and in Sept 2055 people will be wishing they had had bought them at todays prices.

They can’t both be 16.662 mm.
