Mystery tank on my 1951 ES2?

The Indian made tank you've bought is for an earlier ES2, in 1951 they changed from the 2.75 gallon tank to the 3.5 gallon tank. The earlier tank had 1 screw to hold the knee rubbers and the later tank had 2. Your tank looks to have after market knee rubbers.

Here's a picture of my 1949 and 1952 ES2's, you can see the difference in tank size. I no longer have the '52 bike

Hi i have an es2 tank and a 1956 19s tank and the difference in size looks very much like what you have there. the 19s tank on mine is a lot broader and slightly taller at the front basically bigger alround than the es2 one .Baz

Sorry Grant, I didn't read all your comment before replying.

Hi Grant, I recently purchased this tank for my 1955 ES2, early swing arm model. It also has tank mountings that don't line up with the frame mounting lugs.

Although it wasn't exactly correct for a 1955 model, (I was going to braze in some tank badge screw bosses) superficially, it looks to be the correct Norton tank. However the frame lug offset put me off the idea and, luckily, I have now sourced the correct one anyway.

I had thought this tank must originate from another marque, maybe an AMC, but now I see your listing I wonder what it could be for. I can't help ID it, but will be intrigued to see what others say.

just measured the 19s tank i have the mounting bolt holes are five and a half inch centers across the tank both front and rear and both 14 inch centers along the tank. hope you can find what it fits. baz

Yes dave, I agree that from the resarch that i have done, the 1951 tank should be a 2 screw knee rubber. Which is one reason I always felt that my old tank was "origiinal" until I noiticed the odd-ball bolt centers and the filing on the frame bosses. The Indian tank suppliers did make a mistake and supply me with a 1 screw knee rubber which was NOT what I had ordered. I also am trying to get them to do up the same tank in bright nickle instread of chrome. I am hoping to determine if the larger tank existed in Sept of 1951 when my bike was built...I think not.

The bigger tank did come in for 1951. a 3.5 gallon tank with 2 screw fixing for the rubbers. According to my book the colour of the tank for 51 and 52 was silver (not chromed as there was a chrome shortage). The sales picture for 51 does show it with a chromed tank but maybe they weren't anticipating a chrome shortage when it went to print. I don't know of any that were nickle plated. Your bike should look the same as my 52 bike picture I posted earlier. Here's a 1951 Norton sales picture for the ES2.
