RE has made many models over the years, often mixing and matching slightly different bits. Some bikes have fender struts front and rear, some only on one end, chrome bits or not, and every one gets its own name. Complicate that with the fact that the US gets different names than other markets.
The 65 was a model from a few years back.
For the current UCE models there are only 4 and they are easy to tell apart.
The Continental looks like a cafe racer and is bright red. It has a dual down tube frame and a 535cc engine. All the other bikes have a 500.
The G5 has no fender stays and a dual seat.
The B5 has fender stays and a dual seat. The rear fender stays are squarish.
The C5 has a solo seat and fender stays front and rear, the rear stays are round instead of square.
'Deluxe' on any model means chrome bits, notably both fenders and the tank in a chrome/paint combo. Military these days is a C5 but was made all through the years out of many models. I think there are a handful of G5 UCE Militaries in the US from the first year of the UCE but I could be mistaken.
While the frames of the C5, G5, and B5 look similar they are all slightly different, as are other parts like handlebars, etc.
