I guess this forum picture has probably been taken post war. However I did notice the rear mudguard of a pre war BSA C10 (or C11 or C12) with the luggage carrier with the hexagon for the spark plug. So this might be a WD C10.

I saw that also Leon, and I also think it's post war. The 'C' carrier didn't have the spark plug hole on the carrier (I'm sure that's a post war BSA feature). Also no lifting handle and the stays are bolted to the carrier legs.

Not a post war feature I wouldn't have thought..I don't think BSA were still using spark plugs you could strip down in that era...

Whilst not WD perhaps, it was more likely to be a pre war feature...Ian

Ian,

I am with you on that one. My pre war civilian C11 does have a lifting stay. Then again I agree with Ron that the attachment points of the lifting stay should be the same as those at the rear of the carrier. The pre war models X0, B1 and B2 used the same carrier but also had the same attachment points for the carrier. So now I am confused.

Regards,
Leon

I saw the mudguard on the Norton and thought I've seen one of those somewhere, I then realised that it is hanging up in my shed and its still there if anyone is interested.

The Pre war carriers have the hex for dismantling spark plugs and have slightly shorter legs compared to the correct C10/C11 part. They also bolt to the mudguard stays but without the spacer between the central bolt and the mudguard.

I would suggest that has been added in service, it does not have the central bolt fitted that goes down through the mudguard.

Pre-war or pre-posterous ?

The bike is certainly a pre war C10 due to the fact it is hand change.

Don't think these even made it into the 1940 brochure.

The bikes in the photo seem to date from various years, the M20 has panniers etc.

Hi John...I've mailed you ref. the Norton mudguard....Ian

It is a bit confusing. Hand change would mean 1938 but the silver petrol tank would make it 1939. The handlebar attachment means it cannot be 1940. I have a 1940 C11 and I have seen a 1940 C10 in an auction so there has been some civilian production for 1940. The handlebar attachment for 1940 is substantially different from that in 1938 or 1939.

It did make it into the catalogue for 1940:
1940 C10

Sorry, I meant that the C10 with hand change didn't make the 1940 catalogue.

Effectively the 1939 C10 De Luxe (with foot change) become the only C10 available in 1940.

OK Pre war the carrier is! My C10 came with one of those carriers and I had to get the legs extended and the plug hole welded up to make the correct carrier.
