Stolen 1927 Douglas Douglas EW

Hi there , Ray Elbourne here, IMCA member in Sydney, I am writing to as many people as I can to get the word out that our 1927 EW Douglas has been stolen, in Feb 2010, short version of this saga, Dad gave most of the bike to a Guy from Mittagong NSW to work on and do up, but it turned out he later sold the bike to a Collector in the local district , unfortunetly this is all we know from second hand accounts, as the Guy (Dave) has disappeared, we are pretty sure the buyer did not know it was misappropriated, I do have some pics of the bike but not a lot of use if it is in parts. If anyone you hear of, has got a newly aquired Douglas and is missing the head light, gear box and some other parts please let us know. Thanks RAY, at this email or 0408219663, and please feel free to pass this email on to all and any who would help.

Douglas vespa identification
Douglas Vespa 42l2
I am located in Sydney Australia and have a Douglas 42l2 125cc model ready for restoration. I was wanting to know what italian vespa the 42l2 was based on and what differences there were to the douglas version that i have in order to make parts finding a bit easier. For instance tecnica vespa has the VL1T (150cc) with the seat with springs at the rear of the seats (same as 42l2) but has headlight on the fender ? i think this was down to satisfy british regulations re headlight height ? But the 42l2 has the headlight in middle of handlebars like the 42l2. Then the next model change shows the italian version with a different seat (no springs) but the handbar headlights ?? I am confused. Basically is the douglas a bit of a mix of the italian versions of 1955/56 ??
I believe the rear taillight is also round as opposed to the square italian version ?
As it is a 125cc what engine does it resemble so that i can get replacement parts ??? Does anyone have pics of an original 42l2 model ?
Signed..... desperate

Should have taken a closer look.
I recently visited my friend who is a curator of the Southland Museum in Invercargill New Zealand and noticed they had on display a Douglas Motor cycle with sidecar in immaculate condition.They indicated it was a 1940s model but I was sure by the look of it that it was circa 1930. The side car was Zeppelin shaped and a lever poked out of a slit right in the middle of the petrol tank which was very wedged shaped like something from the 1920's. I don't seem to see any pictures of such a machine with this lever poking through the tank. I would think that this alone would date the machine.I would be greatful if one of your experts could GIVE ME A CLUE AS TO WHAT VINTAGE THIS DOUGLAS MOTORCYCLE REALLY IS AND and any misleading representation can be corrected by the Museum Staff. Thank You Edward Case...Dunedin New Zealand.

Good photo of early Douglas on Ebay.
Vendor's Description:
The Douglas Engineering Company was founded in Bristol England by brothers William and Edward in 1882. First they were a blacksmiths shop, but soon expanded to become ironfounders. After the turn of the century with the start of the motor vehicles they soon became involved in the development of engines. The Douglas motorcycle began in 1905 as a prototype engine by Joseph Barter which by 1907 had evolved to become the Fairy Motorcycle. 1914 saw production in large quantities for the war effort and also the start of the 3.5 HP models followed closely by the 4 HP machines. During the twenties many others followed such as the 350cc EW, 500cc and 600cc models and speedway machines. In the thirties a wide range of machines were produced including the S6/T6, Endeavour and finally the pre-war Aero models.

I have an engine which is thought to be a Douglas but I cannot find any pictures on the net of bikes with a similar engine. I guess it is 1930's but I have not found any markings on it yet.

Horizontally opposed side valve, bore about 60mm, stroke? Could be a 350 or 500cc fore and aft fitting in the frame, large finned oil tank in unit with the engine.
Part of a chain guard seems to be cast in alloy with the left side of the crank case, large 12" by 1" external fly wheel, alloy pistons (seized).
The (spark) plugs screw vertically upwards into small chambers which have a small opening to the combustion chamber - there is a dynamo drive and platform with two studs to hold the dynamo to the top of the crankcase.
The timing chest cover has cast in air intakes leading to the inlet valves and fed by a single carb which feeds air and fuel upwards into the air intakes.
The exhaust ports face down & there are two alloy covers over the tappets.
The timing cover and oil tank seem completely different to all the Douglas engines I have seen.

I would like to know what machine it came from and any other details or is it a stationary engine from WW2 or even another make of engine?

Any help would be appreciated.

Here is an excerpt of text that describes the Douglas in your pictures:

The last model made was the advanced and novel 350cc Dragonfly, in 1955. Distinctive looks and good handling couldn't hide the low top speed (75 mph, although a sports model claimed 84mph) and poor low-rev performance. A 500cc prototype was shown in 1951, but never made.

Hope this helps. All correspondence to be sent to takeda at alphalink.com.au regards Michael
