1939 Triumph 3s 350 Side Valve Pre war In totally immaculate original condition. Fully restored 20 years ago “approximately” And recently, I commissioned it using only new old stock components including:
NOS wheel Bearings .
Brake Shoes
All Clutch components Including carrier basket and clutch plates.
New tyres and inner tubes Last year.
Full set of Correct new cables.
Complete rewire using braided correct cabling and fittings Throughout and all electrical systems working perfectly.
New solid state voltage regulator hidden in the Lucas MCR two box and gives perfect service With new gel battery 6V.
Brand-new rubber pipes were needed, including fuel supply and oil supply pipes.
Brand-new oil pump Associated gaskets
Under the mudguards have been wax oiled.
New primary and drive chains with bearings.
Paint work is perfect throughout And in beautiful condition.
I have done 180 miles in the last few weeks and it’s had multiple oil changes using 20/ 50 Castrol classic As also used in the primary chain drive and gearbox.

The whole bike is in wonderful operating condition and very reliable and lovely to ride.

Has a rider and maintenance handbook also.

I also have a brand-new barrel with matching piston with rings and a full brand-new NOS Gearbox gears and shafts which are heavily covered in grease, Not that it needs it at all I just happen to come across a brand-new box of goodies.

Would be very sad to see this amazing rare 3s but I do have to thin out my collection. sadly.
Registered with new V5 non-transferable numberplate.
