Ruby wheelbase is 6'9", Big 7 is bigger, I can't remember by how much, 6" possibly.
The engine capacity of the 7 (750) is often entered incorrectly in continuation logbooks, being confused with the Austin A30 "Seven" or the Austin Mini "Seven".
The engine of the Big Seven (900 cc) is quite obviously different from the Seven.
The head has a cast in top water take off, more in the middle, not at the end, and the dynamo is fore and aft, not crosswise.
I have never heard the Big Seven called any kind of Ruby, either.
