Vintage 1939 Triumph pre unit pre war Tiger 100 bronze cylinder head

I am selling my personal very rare 1939 Triumph Tiger 100 Bronze head.
The condition of this cylinder head is extraordinary.
The guide holes are at standard and undamaged.
There are no cracks anywhere.
The ports have nice short turns and were done with  great care at the factory works.
No damage or modification to the hemi chambers.
Plug threads are nice.
Finish unaltered and original from 1939.
This is my work.
Vintage British racing cylinder heads of all kinds, but I especially love Triumph pre and post war.
I mostly do detailed and complex work including valve seat replacement and prep for land speed record attempts etc.
There are few qualified to do the valve job on these heads as they are so rare and must be treated with great care.
I can undertake this work if you wish with a variety of valve train and valve seat shape choices.
For those of you with a beautiful 1939 Tiger 100 this is the piece to have.
All the best, Leif Racing Engines.
