I might go back a bit too far. This is one of my all time bike heroes.
Funny thing. I was a friends shop yesterday and in the corner is a double Commando stretched featherbed that bears more than a passing resemblance to the above. We talked about it and the owner knows i go to Bonneville and El Mirage. The talk turned to turning it into an LSR bike. Take an awful lot but an intriguing idea.The pic posted by Dean Lowe, #1499. Perry & Lowe? The bike looks like a pair of 750cc Nortons on a stretched featherbed frame. Looks like the negitive is reversed.
I once owned a single engine 750cc Norton drag bike and I was told it was reitred to build a double. I never did find any history on the bike.
