The bb on my pre 2013 Brompton is on its way. Is there a 3ed party BB that fits? Don’t want to change the existing chain set

Should be a standard square-taper unit. SJS Cycles will have stock & they sell Bromptons, so they'll know what you need.

It's "standard" in the sense that it's the rarely-used ISO taper, and rather long. Stronglight or Campag may offer something, or look for a NOS FAG one on eBay. The RH protrusion is fairly critical.
