the douglas resto looks very good and I like the dark maroon.

I have an 80 which is next on the bench and I would like to have details of where you got the seat from as I think that is the best dual seat I have seen paired to a Douglas.

Best regards  DSim

Hi Alan that is great will get on with this tomorrow thanks again

Yes,  the S6 size is 60 X 85 X 5 needle roller
  and the EW I think is 50 X 70 X 5 but both bearings are thinner than the original and
will need a thicker backing washer.
the needle bearing ref is AXK6085ASand AXK5070AS

Any doubts give me a ring 01342-834133 Alan

Hi  alan you wouldn't have a bearing number by any chance but thanks for the information 
Regards John 

Hi Yes, Simply bearings sell a needle thrust race that will fit straight in.

Hello Douglas friends,

Thank you very much for your answers. I also had doubts that these silencers belong to the Mark series. Now I'm sure these don't belong to Douglas motorcycles.

Best regards

Those look like standard Burgess silencers.  Often seen on Triumphs.

These are NOT original equipment for postwar Douglases - they look like aftermarket/ customising items for some other make of machine. The larger silencer in the photo (with B-U-R-G-E-S-S embossed on it) was the standard pattern (for Douglas machines fitted with barrel silencers). They came in 2 sizes - one for the standard road machines (Mk4,5 and Dragonfly) and a longer version with a larger tailpipe for the Mk3 Sports. Earlier machines (T35 and Mk3) had the cast alloy 'woffle box' silencer (which was also an option on Mk4 & 5 machines).

  Hope this helps,
                          Eddie.

Hi Doug thanks for the reply

It is not a commercial bearing, Douglas manufactured them in house.

Many folk substitute a plain thrust bearing made out of oil impregnated sintered bronze (Oilite). Advantageous if the surfaces the original bearing balls ran against are pitted and provides a bit of braking effect if the clutch has a tendency to drag on release.
