Bit of a long shot, but does anyone in the UK have an ISKY 100-GRM Groov-O-Matic block O-ringing tool that they'd be willing to lend or rent out?

I'm looking to O-ring the block on my turbo BMW M20 while I've got the head off. It's an 84mm bore, so it's specifically the smaller 100-GRM tool I'm after rather than the larger 200-GRM. The 100-GRM covers 79.4–95.25mm bores.

Happy to pay a sensible rental fee, cover postage both ways and leave a deposit if required.

I can buy a new one from the US, but thought it was worth asking first as I imagine there must be a few of these sitting unused in engine builders' garages/workshops around the UK!

Alternatively, if anyone knows of a UK engine builder or machine shop that has one and rents them out, I'd appreciate the recommendation.

Cheers :)

Have you tried Munich Legends? It's the sort of thing they'd probably have, or know who may have one...
