Title: Royal Enfield
Post by: Herc on August 07, 2007, 01:42:01 AM
Hi
This is the frst time I am using this forum and I hope the picture gets there.
I have a Royal Enfield, but do not know year or model. I have found D 3230 on the motor block and SA 300 on the carburetor.
Thanks

Hi Herc,

Well, that's a model D you've got there. Must be 1939 or 1940. Is there a broad arrow stamped on the engine? In that case it would be a civilianised ex british army model WD/D.

REgards,
Jan

Thanks Jan
There is no arrow, the surface is quite smooth. Could it be a 250 cc engine?

Regards
Herc

Hi Herc,

Must be a 1939 250cc sidevalve indeed!

Herc,

The specification does look very close to that of the War Department machines and a number of civilian bikes were impressed for military service. Perhaps this one missed the Ministry Inspector's stamp ?

The published contract information doesn't include this motor number but there are gaps.  Have you found a frame number ?

The saddles have a German look. Has the bike turned up in Continental Europe ? If so, it could well be one of the 20,000 plus motorcycles that the British Forces abandoned in May / June 1940, many of which were used locally afterwards.

Have you tried scraping the paint in odd places to see if you can find any khaki green or, just possibly, pre-war R.A.F. blue ? If it's from a Military contract and it's never been shot-blasted then there must be some original paint somewhere such as inside the headlamp or tool box etc.

Another clue might just be the light switch. If it has a "T" position (tail light only) that could hint at some military history although I'm not certain that early Model Ds would have had the military switchgear.

Rich.

Hi Rich,

You could be right, the kneegrips look a bit foreign as well I think... Would be nice to know the frame number. This number is usually stamped on the headstock, at the left hand side. Will you keep us informed Herc?

Cheers,
Jan

Hi,

Just noticed this: I have some pictures of civilian D's, and these all seem to have a dynamo plus coil ignition, the 1939 catalogue doesn't mention a magdyno either. All the military WD/D models definitely had a magdyno. This bike also has a magdyno. Retrofit? Or is it indeed a civilianised WD/D ?

Cheers,
Jan

On the engine close-up picture that I posted,  there is a "D" for the model, a "/|\ M11" marking which is the military inspector's marking, and the engine number 2344. I was wondering if Herc's engine (number 3230) also has this inspector's marking, which would definitely make it a WD/D.

Thanks all for good feedback and I'm able to add more details.
It's a 4 shift gearbox with a foot gear shift. I have opened the cover and found the sidevalves. It's a missing item on the engine. I believe that should have been a dynamo, no sign of a coil. Hard to find any frame number on the left side of the headstock. I do not know the right spot for it and it looks like it has been welded on a reinforcement on the top part of the frame in front of the petrol tank on both sides.
The colour is black all the way through, no sign of army green or anything else. The light switch on the headlight is a LUCAS marked with OFF - L - H

no sign of a coil.

There should not be any ignition coil as the bike has a magneto.

Hi,

I've been doing some research into the model D as I have one also. Yours appears to be a Civilian modal but I'm about 99.9% sure it would have been pressed into military service (or possibly some other war effort not directly asscociated with the war office). The magdyno isnt the original as the straight carb stub was only used on the coil ignition models. The magdyno models have a bent stub.

Hope this is of help,

Chris.

Hi
I have been trying to get an Illustrated Parts Breakdown for the bike, but with little luck. If anybody out there have a copy please let me know. What I need is an Illustrated Parts Breakdown and a Workshop manual for a 250 cc model D 1939/1941 Royal Enfield.

Herc

Unfortunatly the parts list is non illustrated for this model, which is a pain.

What is is you need to know?

Also, Could do me a favour and take a photo of the way the battery carrier fits to the frame, I don't have a battery carrier on my bike and I can only see one mounting point for it with no idea how the battery carrier fits to it.

Also, I think the serial number is on the right hand side of the headstock (thats where mine and other WD/D's are found)

The welded reinforcement (fork stop) on the top of the frame is correct as with out this, the forks would swing around and dent the tank.

Thanks for information
Yes I have found that there are no illusttrated parts breakdown from that periode. Anyway if there are no bits and pieces illustrations at all I will have to guess the name of the part I am not familiar with or I could add pictures when ordering parts.
The problem often is that people having parts for sale do not always know what they belong to.
I am adding a picture of what I believe is the battery carrier. Hope that is what you need m3bobby.

Herc

Hi Herc,

Can you email me at m3bobby(at)hotmail.com

Thanks for the photo, I'm still not 100% sure how it fits to the frame, but it definatly is a start. For some strange reason, not many model D's still have the original battery carrier.

Cheers, Chris.
