Alright boys ..

I had a look at the Sierra members earlier. This is the situation ..
They are in the section for "about to be killed off" stuff. There are 10 left of LHS. LHS - Finis-1644593. 5 have gone this year (including one this month)
RHS - Finis-1644591. None left in UK, 12-ish in Spain, 1 in Norway.
It is possible to get the part sent from Spain, I could do it .. It would prob cost net plus postage.
That's it .. All gone after that.
Quite a substantial part. From rear exhaust hangar to front is 5ft 8" long. Spring cone seat is 1/2 way along, and it has the forward mount incl.
