Yes, it's wrong to advertise a bike as "1913" when nothing about it looks anything other than 1920s. "Selling on behalf of a friend" is a pretty tired excuse.


It depends on which wheels you have fitted. Early Dragonflies had Douglas wheels - later models had 'British Hub' wheels.

I have just had a look at mine and there is a nut to hold the speedo grearbox but no spacer. Nut goes against the swing arm. There is a 10.5mm spacer outboard of the brake plate on the otherside. Does your chain line up OK?

Bellow photos of our Douglas 2 3/4. On the crankcase is stamped 1915 but engine number speak 1917. As here was solved most probably remains of 1915 Douggy were bring it back to Douglas facctory during WW1, from this 1915 remains new machine were assembled in 1917 and send back to front. Bellow as it was found and how it is preserved, just with little clean.

Dear All

What do you thing about this Douglas project ? In description is that it is 1913 year. Based on photos front forks , rear carrier , saddle fitted to the frame looks like early 20s (maby model TS) . I will be grateful for your opinions.  I'm looking for WWI Douglas project so this is the reason why I'm asking about it.

Stay safe
Best regards Artur

Oil pressure is not entirely essential for plain bearing motors, as long as there is is some flow,
even a mere trickle can suffice.

A number of early plain bearing motors, inc the T Model Ford and early Hendersons
only had a splash lube type of oiling system - and did some big mileages.
Provision is made for the splash to get to EVERY place where some lube is required however..
A lot of early roller bearing motors in the veteran and vintage years ditto.

What is troublesome is if the oil splash is absent for any length of time.
As horsepower outputs rose however, pressure with flow was a useful improvement to reliability.

Are there pics anyplace of these prototypes ?
I didn't realise the Dragonfly was such a latecomer to production.
Hi all by any chance does anyone know the width of the spacer collar in the back wheel between the speedo drive and a washer, part number 31553 item number 14 on page 39 of the parts book.

Cheers Kevin..
