Spare trumpet base?

[LordGrover]

I'm on the scrounge.
I'd like to borrow or exchange a trumpet base if anyone has one lying around please? What I'm planning to do is to fit the ACT Superflare trumpets to the 'new' base and do a before and after run on a rolling road.
Thanks

Isn't the TVR community great?
Within an hour I had one on its way and offers of another two.
Grateful thanks for the PMs.
