That panel doesn't look right to me. Originals were fiberglass and most colors were flake blue, red, purple, I think the only solid color was yellow. The front engine mount would have been painted black. That avatar pic was taken in '72. Here's what it looks like now. I have lots of detail pictures on photobucket. You can search around from this pic link.

Hi Brian.

Our Commando 131453 as NOC says is an "S" type and dates from 18th March 1969.

New Norton Commando- ID Help please.

We have another "S" type 20M3S/132... and dates May 1969.

Hope this help.

I'd hate to disagree with such an authority as L.A.B., but it looks like an early Roadster to me - it has the wrong oil tank and headlamp to be an S-Type - but then again it appears to have later style clock brackets, so maybe it's a bitsa.

It has the later headlamp brackets but still the old-style yokes, it definetly is a bitsa in some respect. The battery carrier assy looks like the early version for the central oil tank with the vertical sheetmetal section removed so that a late-style oil tank could be shoehorned in. I'd strongly suspect that judging by the pics a 750s with several incorrect parts is far more likely than a true bitsa. Looks like a rather straighforward restoration project. One thing to check IMHO is whether the top yoke has those threaded bosses on the underside to which the halo struts were mounted. AFAIK the Fastback still had the Atlas-style yokes, at least they have different numbers in the parts list compared to the 750S.

It might surprise him but I agree with LAB. :mrgreen:

Mine is 20M3S143997 and is a 1971 Roadster so I am not sure the "S" designates S Type?

All models eventually got the timing cover points assembly, therefore, all Commandos would have had the '20M3S' engine prefix by late 1969, so the presence of the 20M3S prefix doesn't necessarily make it an S Type, however, as I stated previously, the only other two models in production at that time (March '69) would've had the '20M3' prefix.

The 20M3S prefix was finally dropped at the end of 1971.

Difficult to tell exactly from the photos but it looks as if it could be an 850 Mk3 battery carrier/tray.

(Also an 850 Mk3 rectifier mounting bracket, 06-4974)

Yes, you're right: The central oil tank version would not have the vertical LH section where the battery strap is attached to which is visible. It definetly is not the post-71 version with the longitudinal vertical section between battery and oil tank.

Tim,

Thanks for the insight and input. Looks like I have a long road of parts hunting ahead of me.

Thank you for the additional insights and information. This site and its members are a wealth of information.

Thanks Tim!!
 
As stated it certainly looks like an 850 Mk 3 battery carrier.
If it is, then you will have to relieve the bottom of the side cover to fit around around it, assuming you haven't got a mk 3 side cover that is.
Good looking project !

As mentioned above, seems to have parts from several years. The VIN is from 1969 which would have the center stand attached to the frame rather than the gearbox/engine plate (1971 onward feature). From the NOC website "The 'S' Type was introduced at the same time as the 'R' and made its debut in March 1969. The styling is of a type more to American tastes than traditional British with the fitting of high bars, not a very large petrol tank, ungaitered forks, and a high exhaust system with both pipes on the left hand side of the machine. A shield was a necessary fitment over the pipes for the protection of riders. The exhaust line being a little shorter than that of the Fastback, gave the 'S' Type slightly different power characteristics. Other distinguishing features are a quilted finish to the dual seat and a chromed 'crash bar' around a smaller styled headlamp. The 'S' Type was also the first Commando to have the points driven directly from theend of the camshaft (20M3S S Type first and all later Commandos until 1972 when the 20M3 designation was dropped) and hence the rev counter drive, which used to be in that position on the twins, moved around towards the front of the engine. The 'S' Type was the basis for the Roadster model which was virtually identical except for a low level exhaust. The INOA Tech Digest states that the 'S' Types fell within the range of Engine Nos. from 131257 to 135088."

....a chromed 'crash bar' around a smaller styled headlamp...

The S Type had the standard 7" Lucas SS700P headlamp.

The 'SS' (and Hi-Rider) had the smaller MCH66 headlamp (no 'halo').
 
About S type i can say that i have found on my bikes that when the tank is metalflake painted the rear tail light mount was grey while that the tank was pastel color the rear tail light mount was black.
I dont know if is just a case.

Hi Brian,
The S type yokes must be both grey (your bottom yoke is black like 69 Fastback and R).
Look at the top yoke, it must have under the two threads to fit the head lamp ring stays.
The bottom yoke (grey) must have the long studs to fit the lower side of the head lamp ring (Andover supplies).
The chain guard and exhaust lockrings are later not of the Stype.
The barrells must be grey.
The rear shock absorvers must have the upper chrome cover.
The other fans just told you about oil tank, battery tray, exhaust system,center and side stand, head lamp mounts, instrument cases, etc.
Hope this help.
Ciao
