After extensive research, I have been able to find out that Gills 58 had a:400/4 Honda and a BSA Starfire but it was too unreliable.
He had his leg crushed by "white van man" pulling out of a side road without looking properly and had 19 operations, including bone and skin grafts, but managed to resurrect some of sporting career, such as it was (cricket/tennis/badminton) but had to give up football and hockey as another break (already re-broke 3 times) and they told him they'd have to amputate. BUT HE DOES NOT LIKE TO TALK ABOUT THE ACCIDENT OR THE REPERCUSSIONS.
First they came for some stupid bristol statue - i said nothing
Then they came for the gandhi statue - i said nothing
Then they came for the Churchill statue - i said nothing
Then they came after penny lane - ffs this is the Beatles man, dont go after my music
