Question about Douglas brochure

[Dave]

Steeve emailed this brochure and question today.

Hi, I’m writing from France. I own a very old Douglas sale brochure, surely from the 20’s, and I wonder what model is … (see the attached file)

Could you help me to find it ? This 2 pages folder is for sale if someone you know is interested ?

Thanks a lot, I wish you a great Christmas time

best regards

Steeve

I think it would be a 23 model CW - as it has the Douglas rotary carby which I believe was only available on 23 models

[Doug]

The 1923 had a different style brake, an inverted v-shoe bearing on a very small rotor.  Those half-size dummy belt rim brakes came out with the 1924 models.  Yet the saddle nose spring is the shape seen on the 1923 models, and not the '24s.  So a 1923-1/2?

Further to Doug's response I believe the frame types were mixed in respect of the front saddle spring. My 1925CW has the flat clamped spring as opposed to the alternative hooked spring bolted into a block welded onto the top frame tube. The Douglas alloy rotary carburettor was also used through to 1926.

The brochure has now been listed on eBay.

Hi. I would think the bike is 1925 or later. Rotary carb as stated carried well into 1925/26. The flat seat bracket indicates later than 1923. The giveaway to me is the rear sprocket. My original 1924 sales brochure shows a very different design (straight spokes) on the earlier CW models -  Nev.
