Original norton fuel tank identification?

Good day to everyone, my question for everyone is how would one tell if they have an original steel norton fuel tank? Roadster in specific. Not sure how big of a deal it is to know, but personally I would feel much better knowing if my tank is an original or a "re-pop" before laying out the money to have it painted. The underside of the tank under the foam pads is candy apple red which according to my research tells me that would be one of the correct colors for the year (1973). And the last part to my question, isn't here any other advantage or benefit to starting with an original steel tank as opposed to a reproduction tank other than personally knowing its original? It looks like someone tried to smooth out some of the welded seams and failed terribly, so if it would cost more to make this tank right than it would to start with a new one then the choice sounds pretty easy. Is there a known reproduction tank that is better than others? Ok I guess I had more than one question today, thank you for any help anyone may be able to provide!

With original paint under the foam pad, sounds like you have an original tank. Value of an original tank is you know it fits correctly. The disadvantage is it's old and used so potential for corrosion, dents..etc. I'm about to have an original (candy red) tank painted signal red for my '72 roadster. I also have an original steel right side cover and a left side reproduction from Andover. My point on the reproduction is it needed a bit of grinding to fit past the frame tube, but once fettled looks and works great. I have no experience with the reproduction tanks. The pictures of some of the India made tanks on ebay don't look like they are the right shape.

Why not post some photos from several angles ? There were 'seamless' Roadster tanks with fabricated bases used on the Mk3s (at least) ? Could it be one of those ? I have one and I don't think that it has as nice a shape as the earlier tank. It's not baffled either.

you can always make it look right, dent or no dents.. Most important is the condition of the inside.... Has it been "lined" with epoxy, is it rusty inside, and does it hold fuel.. Check for leaks with a cupla litres of diesel cos it will "creep" out of any holes over night..

Show us the weld seams that have been "smoothed out"...

The reports on Quality of Indian made tanks does not inspire confidence , as you can not be sure what will arrive

If you have a Genuine tank in repairable condition I would opt to leak check /Tank seal and re paint

But I have also heard EMGO have re tooled and initiated new production ( Taiwan ) Norton Roadster tanks which are apparently on route to both the UK and USA distributors
if the new EMGO Norton press tool quality is as good as the T120 replica they already make , fantastic we will have a good quality economical replacement available
