There must be some somewhere.
Manners has them part [RH part No 136203 & LH part No 136203E] exchange/reconditioned at £449.04.
But I'm sure i have one in a cupboard in my shed... but they are handed so i need to know which side you need?
I think the standard ones are off another car [i.e. parts bin] and machined for the handbrake linkage to fit.
Get in touch with me if you want to take it further.

Try pastparts.co.uk in Bury St Edmunds for all things regarding brakes, they are excellent.

Rear callipers have been elusive for quite a while. Sadly they fall into a category of parts that may stay elusive.
Not enough need to warrant tooling up for production so people have to change from original spec to get around it.
It’s the sort of thing that people have on the shelf but are fearful to part with “ just in case “.
The model is just too popular and supported by suppliers for the club to throw money at.

Barry Thorne used to have a list of equivalent parts from other cars. Not just brakes but all sorts.

Alternatively.....
I’m told that he rear axle from an MGB fits in place exactly.

Doesn’t the MGB rear axle have drum brakes ?

No idea only repeating what I’d been told. I can’t see anybody would do that, would they ? :(

The pistons are MK10 Jaguar, the caliper is peculiar to the SP purely because of the hand brake arrangement, if you can find a caliper that is similar for the mounting holes and the disc diameter it may be possible to weld on the handbrake lugs, welding has increased in capabilities since the SP was produced. Providing they are not cracked the caliper can be over bored and a sleeve shrink fitted in place to the original size or a similar size easily sourced if bore corrosion is the problem.
