Thanks for posting this.
Certainly not a double value for a pump!it doubles the price of the bike when it is included...
I have your same tyres pump on my N15/G15/33 .Here are the pumps on my '68 Commando (Fastback) and '69 Commando 'S'. They are a little different from Piero's. Both have metal loop foot 'stand'. The '69 is the original according to my friend, who was the original owner for 48 years. The other I found in England. The only difference is the '69 is all metal where the one on the '69 has a plastic 'handle'.
I also have another that is about 1 1/2 inches shorter and will not fit between the frame lugs. Other than that is identical to these two.
