Umm.....
I have:-
MFL323 (F range, 32amp TP) - No good for you.
MGL201 (G range, 20amp SP) - No good for you.
MGL321 (G range, 32amp SP) - No good for you.
I do have however the BILL equivalent of the MGL range, the TLG range.
I do not have a TP MCCB, but do have 3 x SP MCCB's. These are not MEM, but the BILL equivalent (identical).
They are the TLG1001 (G range, 100amp, SP). As I say, I have three of these which would sort you out until you recieved delivery of your other. I took these out of a board a while back when re replaced three single phase submains with a three phase submain. Make me an offer.
