750cc.
A few photos might help us identify 6V or 12V charging system.

That bike is 12 volt, positive ground.
Nortons after serial 121000 (mid-year of '67 model run) switched to distributor ignition. The coils should be 12 volt, unless a previous owner installed a Boyer ignition.
My G15CS is just 150 or so units away from your CSR.
Any small 12V battery should work. The original would have been a Lucas PUZ5A, so one that size, or ideally one a little bit shorter, as it needs to fit inside that hole in the toolbox without the terminals hitting the metal.
Best source for literature is Christian's archive, at jampot.dk, though the engine, forks, clutch and wheels & brakes are the same for Atlas and the CSR. The CS has the same rear wheel as the Atlas, WM3/18, but heavier spokes.
Some late CSRs were also badged and sold as the Atlas 750SS.
Transmission is also the same internally - just the main case has the lower mounting lug in a different position.
The G15CSR/33CSR changed year by year. If you're trying to restore this bike and want it to look right as a late '67, do a lot of research. Large chrome tank/small red tank, large chrome fenders/small chrome fenders, chrome headlight/black headlight, chrome ears/black ears, chrome chainguard/black chainguard, 3 or 4 different handlebars, 2 or 3 different seats, etc.
One think I THINK is common to all CSRs is the reverse cam plate and gear numbering on the trans outer cover. This allowed the mounting of the CSR shift lever backwards to reach the rearsets, while maintaining the standard AMC 1-up, 3-down shift pattern. As I stated above, this same model was marketed as the Atlas 750SS in '66 or '67 (not to be confused with the featherbed 750SS or the Commando 750SS). This late Atlas 750SS used the same AMC frame as the G15 and 33 variants.
