here is the way it boils down,
The model designation is ...TR7RV
it is a TR7-that's a single carb 750.
it's a "R" for road model.
It's a "V" for 5 speed.
then the serial numbers...
"A" which is for the 1st month of January
the "H" is for the year of 1973
and the individual of the numbers are the bike.
as for the bike, It should be a OIF, disk front, drum rear, right hand shift, with a single Amal 932 carb, and is rather rare and considered to be one of the more desirable of the OIF bikes.
And OIF stands for "oil in frame"
