I have the great misfortune of owning two McIntyres, neither of which is complete.
The most complete one is missing its original bell and barrel. The other one is missing all of the keys on the upper stack.
I believe they are NOS pieces, unfinished when McIntyre went bust. Neat piece of clarinet history, but completely useless for resale value.
On a related note, whoever ends up winning that one in the auction has their work cut out for them in terms of repadding it. Phil and I have both tried and it's nearly impossible to get the McSystem key springs to actually work. Crikey.
