Quote from: EW-Ron on Yesterday at 08:3063 quid eh ?  How much would that be with tariffs today !

Good question Ron, I have no real idea so searched Google for a rough answer. The brochure on the New Zealand "Barnstormers" website was originally from William's Bros in Sydney, so hard to know if the price was in Oz pounds or NZ pounds. Anyway found these inflation calculators on the RBA and NZRBA websites and found out that they estimate 63 quid in 1925 would be worth about AU$6.314 in 2024 and about NZ$7,969 this year.

I had no real idea what it would come out as but that seems sort of about right, comparing it to say medium range small capacity motorcycle of today???. No idea how import tariffs would change that?...a tariff of a 125% would make it way too expensive I would think, unless the Penguins on Macquarie Island have worked out a way around that .........

I saw the Zoom-Zoom exhaust on Harry's bike and then realised I had seen something similar in a picture of custom Douglas machines by W.G. Coram. There is a picture of it in this thread (originally posted on the forum by Tony C, I went looking for the original post but did not find it - will try again later).

https://www.douglasmotorcycles.net/index.php?topic=7561.0

Eddie mentions that Coram made zoom-zoom exhausts in the thread as well so I assume it could be one of their products. The one on Harry's bike looks a bit shorter than the one on the postcard but otherwise similar?? Also the non-Douglas footboards on Harry's bike appear to be similar to the Coram ones.

I have found a 1923 catalogue picture of the TS and noticed something about the seat mount spring, just investigating that and will post about it later - as you say Ron, you cannot be too careful about what you see in advertising pictures! 

Cheers

Not sure if it will help but do have a look at my carb picture post for 26 August 24. I have tried to copy to here but with no success .

Has the LDMCC post war spares got any of the carb bodies they had cast left ?

Indeed, it was common practice - through much of the motorcycle industry - to take a photo of last 
years model, employ an artist to add or delete new or old features, and use this in next years brochure.
This was necessary to allow for the often long lead times in getting things printed,
or to have brochures to hand out before new models were in production.

This often results in bikes that seem totally devoid of cables, wiring or petrol and oil pipes.
Or in some cases, models with features or finishes that were never actually produced.
And some brochures are famous for using photos which have not been updated, so of older models.
A trap for folks who restore strictly to brochure specs. !

Cannot speak specifically for Douglas here though, have not compared in detail.
That acetylene lamp just above does not appear to have an acetylene supply though ??
Otherwise a great pic find.

Hi not open Mondays 

Colin

Hello Alister,

I just happen to see your ad, and love the machine. 

I am contacting you from the USA  - Arizona.  I'm not the guy you mentioned above.

That's almost the exact bike I have been hoping to find. 

If you care to name a price, I'd like to know what it is.  I can arrange the payment, collection , and shipping from my end if necessary but would welcome any help or advice if we can get to a deal.

Here is my contact info if you would like to email or text.

No worries, Harry, glad to be able to help. Great picture of your father-in-law on the bike, thanks for posting that!

Trying to nail down exactly when Douglas changed certain specification from year to year is often difficult as they tended to use up old stock left over into the next years models and the advertising documentation, they produced, doesn't always reflect the exact model they sent out the door. Also, there are some artistic licenses in the pictures in the brochures as they have been "touched up" to clean up the pictures for publication.

The saddle mount you have is a common Douglas feature from that era and was used on the TS and OB models. Some refer to it as the "hook spring". It generally is found on the circa 1924 models. Sometime during this period and later it was replaced with a flat spring rather than the hook version.

I have attached a 1925 sales brochure picture (from the Barnstormers website in New Zealand, https://www.barnstormers.co.nz/2227/1922-douglas-sales-catalogue/). I suspect this is actually a 1924 picture of TS (?) rather than the 1925 variant, but I don't have the 1924 sales brochure for comparison (or the 1923 one for that matter).
 
I was wondering if I could ask you a favour, would you be able to get the gearbox number off your machine? I have been investigating and collating the relationship between frame / engine and gearbox numbers for the 2 ¾ hp models.

https://www.douglasmotorcycles.net/index.php?topic=9253.0

Your bike appears to be a very original example (and does not appear to be in the LDMCC Machine Register) and therefore the gearbox is most likely original and I would be able to use this information to help confirm my trendlines. If you don't want to post the number on the forum that's ok, please PM me.

Cheers

Hutch
