The SRM pumps aren’t in stock and could be couple months or longer is there a similar alternative or has anyone got a good used pump they could sell me please, just to get some miles in.

G'day Mike.
Why don't you reco your old one?
Easiest way just take the end plate and extension housing off (do not remove the gears). Use a thick piece of glass and wet&dry paper and lap the gear marks out of the plate & housing. Care when assembling use the glass to keep the parts flat and tighten the screws a little at a time and spin the pump between each tighten. If it binds back off screws and start again.
Better than waiting weeks to find a new replacement and if s/hand I'd do the above anyway.
Cheers

But as Musky says, DO NOT remove the gears unless you've marked them indelibly. They don't go back together haphazardly.

Hepolite/Wassell do a cast iron bodied pump which is worth a consider. Anyone bought one lately? They were priced at the same level as the SRM pump.
Swarfy.
Additional. Like SRM a quick looky on t'net would indicate that for the time being both are on back order from the usual suspects.
