Repro Marelli V12 Distributor Caps

[Jaguar5993]

Hi,
You might already know that original V12 Marelli caps are virtually impossible to buy new, although I have just seen a new original Magneti Marelli Twin Spark Distributor Cap (Genuine NOS) Porsche 911 RSR, 914/6 GT
at £1,200.00!!
These caps were also fitted to the Ferrari 365 and 400i V12 engines, as well as some V12 Lambo’s.
Second-hand ones are £200-£500!

Came across this on eBay…Jaguar XJ12 XJS w/ Marelli Ignition Distributor Cap Facet XD352.
As you can see, it has the Magneti Marelli style brass electrodes compared to the other new repro caps available with the thinner steel ones.
Is it worth the risk? Has anyone recently bought one?
Obviously, it’s from China, but this seller does not have a long eBay history or much feedback.
Maybe it’s too cheap (£79) to be long lasting.
I have previously heard of Facet fuel pumps, but not dizzy caps.
If it came from SNG, David Manners or other Jag part suppliers, I might be more confident in ordering one, but if they did, I think it would probably be more than £79.
Good luck.
