I have a 1955 Norton single. It seems to be a Norton ES2 frame with a 19S engine and I assume matching gearbox. Engine number: 61300 K9 82 /113 and Frame Number: K4S 50225
Is this an ES2 with a 19s engine or are ES2 frames the same as the frame of a 19s? I have looked at photos of both and they look the same. the difference seems to be the engine size.
Any help would be appreciated.
19s
Yes a 19s. engine. My first Norton was a 55 19s original. Noting the K engine number It should have a laydown G/box originally but yours not original or factory built. Yours is a Norton and date should be when the frame was made.
Sorry I miss understood your question, though I did read it.(Not enough emphasis on the year. and I've not been well for a while so my apologies, sorry.
My focus was on the 1958 / F / bed 19s. But that will be another debate. ( few I believe were built)
Thanks for the info, Mick.
Frame: 1955, hence date
Engine: 1955 Noting the K in the engine number. (K - 1955)
Bike is therefore an ES2 with an engine change.
G/box. I don't believe these marched until later Commando's, such as my Mk3. Philip H wrote that these were made in batches and used as required.
Sorry for getting mixed up.

Box
Yes, Mick.
Both would have had a laydown box ( Number not an issue) That includes the 350 model 50 if not all road going Norton's. During 1956 the factory moved on to the AMC box.
I read 55 as 58 initially.....Should have gone to spec s........
Sorry about the brain fog earlier, but we got there.

I believe a few of these were made BUT that is only from Memory.
