M.G.Vig - I've got an old bicycle pump you can have for the postage! That head is nuts - who in their right mind would want to pay more than £100 max for a dirty 8 stud head with "no visible cracks"?
Tire pumps with authentic "Triumph" markings have been thin on the ground and pricey for a long time. They were going for over $100 20 years ago. Generic ones without the factory logo go for considerably less.
And if you are restoring a '59 T120 and need the head with the correct date then you are likely willing to pay whatever it takes to get it.
