Ta very much! It's more or less symmetrical, maybe +/- 1mm but don't think that'll make a difference...

If it's symmetrical then go ahead and buy a symmetrical BB. If not then go down an internet rabbit hole looking for the assymmetrical one.
I dunno if the 110mm un300 that @jtfh linked is symmetrical but see further up the page for my discussion of the 110mm un55 not being symmetrical.

Should be fine.
You could check spindle protrusion on each side, i.e. how far outboard from the frame's BB shell the current BB spindle extends. If it's symmetrical then go ahead and buy a symmetrical BB. If not then go down an internet rabbit hole looking for the assymmetrical one.
