It also came with a bunch of old Norton tin and spares of various sorts which will definitely come in handy for horse-trading down the road.

Both excellent and valuable points.

Let me give you fair warning in advance: It ends up costing more than you think, to build a bike starting with leftover spare parts; even when you have most of the main/core components!!!

No need to ask HOW I know this...

Hah! Yes, a lesson also well-learned from my Enfield. Thankfully most of the old Norton stuff is for bikes other than mine, so I will just use it for trading value.

ImageI drug this project home last winter. 1967 N15CS, matching numbers and clear title. The motor turns over with compression. Appears to be a Commando head? What do you think? I'm looking for the left battery cover, brought home 2 trailer loads of british bikes.

Looks to have a commando instrument pod too, so its had some contact with a Commando sometime.
Can't help with the cover, but they appear on ebay now and then, if you don't track one down.
You'll need something to bolt it to ?!

And welcome here.
We look forward to seeing pics of progress.

Oh, yes. I did find the battery box, less the cover. Thanks ks for the welcome. I've been told the front end may be Commando also.

Yes, those fork tubes do look to be hard chromed, so that would likely be Commando.
That would make them ~2 inches shorter in the fork tubes ?
Might be no bad thing for road use.
Yokes look like they are Commando too.

I agree with Rohan, the whole front end looks like Commando to me. I'm not convinced that these fork tubes will allow the bike to handle properly. The triple clamps should be the older style clamps with the stem in the bottom clamp and a screw on ring underneath to facilitate fork gaiters, there should also be longer chrome fork seal holders and some other bits and pieces like headlamp ears and one-piece instrument holder. The rear mudguard also appears to be from a Commando.

The left side battery box and cover are quite hard to find, although they are now making repros in India, there is also a separate battery bracket which fits inside the cover and bolts to the frame with it's own mountings. This looks like a very nice project. My own G15 project was less complete than this but I managed to get all of the parts with a bit of patience and scouring the internet.

Yes, Commando head and look like Commando forks.
The rear wheel may be Commando, too. The CS had very heavy spokes, thicker than Atlas, and 18 inch rear rim. The G15CSR had the same size spokes as the Atlas.

Rear fender looks to be Commando, too. On a G15 there's a bracket that supports the leading edge of the fender by bolting it to the vertical frame member.
Image
Bracket is sort of 'J' shaped and can be seen just at the bottom of the fender, bolted to the timing side of the frame. Also notice how heavy the spokes look on the wheel.
With the Magneto, I assume its an early '67? Change to distributor and concentrics came mid-year at bike number 121007 (the first P11).

Serial number 118735. I pulled the rear fender out of a heap of fenders, so it very well may be the wrong one. I will do some more digging. Thanks so much for the replies.

Not to restart a dead thread, but I just picked up a real clean 1964 n15cs rolling project in upstate NY. I need to collect the missing parts and start the build. If anyone has info on parts or repair manuals I would appreciate it.

A 64 would have the spigoted barrels, magneto, and monobloc carbs. The front forks should be all norton, long roadholder, seat would have the white piping around the top.

Walridge motors in Ontario is a good source for hybrid parts and AMC Classic Spares in Bedfordshire, England is a great source for AMC parts.

Most of that bike is AMC except for engine, forks, and wheels.

Hi Bill.
Please, why the N15 fork stanchions are a little bit longer than Commando one?
Thanks

Off-road longer suspension travel.

Hi.
I understand, but i think the N15 is not a very off road bile!
