If you have any info on Gary Littlejohn's please send me some Email.
One word description: BEEFY! Head tube gusset, down tube/seat tube gusset, rear tri-angle gusset and look at the back end of that frame!?
This sucker looks like it should have an engine on it, I think the designers had been looking at one to many motorcycles.
Your wondering if you have a Gary Littlejohn? Look for the two holes in the front gusset like in the photo above, that was their Trademark but some others used a similar style.
