Hi Members, i have a ( 69 Mercury basket case) original fuel tank is beyond repair, the previous owner aquired a tank off a Triton with the same features as the Norton tank, i heard that Triumph had used these tanks when they used the Norton featherbed frame. the cap opening is on the left side. Can Members share any light on this subject.
Regards Denis Curry.

Mercury/Norton fuel tank
Thank you to the members who replied to my post re Mercury fuel tank. I have posted some photos below of the fuel tank and any further feedback would be much appreciated. Apparently Triton used some of these tanks on the slim line frames. Hopefully Norton badge connections/inserts are still intact.

The small tank was also used on the Atlas and ES2, possibly as an option, in the North American Market, maybe other models as well, the ES2 looks particularly strange with it on. I have one and the bottom pressing looks to be the same as the standard one, I will have a look if it really is shorter or not.
The seam could easily have been filled and concealed, I don't know why they left it like it is, because it looks a bit of a dogs breakfast.

Mercury petrol tank
Denis,
My 1969 Mercury has the filler cap on the right hand side and would agree with Robert's info. I've wondered why the filler cap was moved from left to right on later machines; perhaps selling to the USA meant that with driving on the right the filler was nearest to the petrol pumps?
Either tank with left or right hand filler will be fine, unless you're entering concours shows!

A Wideline tank-
will fit. I know, my first-ever Norton, a 1961 S/L 88 had no tank when I found it in 1970. The first tank I could get was a W/L; of course it doesn't have the 2 front fixing bolts underneath, but with a go-faster ally strap and rubber mounts it served until I got round to finding a S/L tank.
For obvious reasons a S/L tank does not make a good fit on a W/L.

Left or right
Having the tank cap on the right side makes it easier to get it full if you have it on the side stand.

Confusion?
Triton was never a manufacturer - it just implies that someone has put a Triumph engine in a Norton chassis. Similarly, Triumph never used Norton tanks.
Anyway, any slimline Norton tank will fit your frame.

Looks like it may fit , I think Dresda Triton may have been recognised as a manufacturer , certainly made lots of Tritons.

Mercury AMC2 gearbox
Hi members .. I have a 69 Mercury basket case with matching frame and engine numbers and the inner gearbox case has the same number stamped on it. Is it unusual to see matching number displayed on the inner gearbox case? See attached photos showing matching numbers. If anyone can throw some light on this for me, it would be much appreciated.

Mercury matching numbers
Denis,
My 1969 Mercury has the same three matching numbers as well.

As built, all Mercuries had three matching numbers. Similarly 750 Commandos and 750 Norton Hybrids all matched. I'm unsure about the AJS/Matchless Hybrids. Cheers, howard

Any std slimline tank should fit a Mercury. The petrol cap on the left side just usually signifies that the tank was made before 1963 , The only std slimline tank that wont work is that of a Manxman which is much smaller with visible seams and needs a different seat length. And worth a fortune !!. Not likely that you will find one spare.Wideline tanks dont fit and have the strap fixing down the middle. A custom tank from a triton slimline should fit but may be non std length and need a shorter /longer seat . Some tritons are wideline ,so no good.
