Does anyone know if it normal to have to remove the whole rear sub frame, seat, mudguard to put the tank on and off ?

As I recall, the '59 Bullets didn't have a rear subframe. I would find it highly unlikely a rear subframe would have to have taken off to remove the tank on any bike!
The rear tubes were welded to the backbone as is common on most bikes. Even if they were bolted on up there, the tank would have to be removed to get to the bolts... but, they're not.
Just ran across a picture of a frame so you can see where the rear tank mounting bolt https://www.facebook.com/photo.php?fbid=10151836490923918&set=pcb.625738154139469&type=1&theater

The seat might have to come off but after it is, removing the fuel tank should be pretty straight forward.

Thank's for the replies, taking the seat off is possible, but the nuts and bolts that hold it together are very difficult to reach, and there is no room for spanners or sockets. The subframe clips in at the front and fixes onto the top suspension mounts. The picture shows the front of the frame with the seat mounts sticking up.

Thats more of a seat mount than a rear subframe. The rear subframe is usually considered the bars that run back to hold the shocks and loops back down the the main frame.
I guess we got lost in verbiage.
But to go to the original, it's not uncommon to have to take the seat off to get the tank off. In fact, it's the usual prpcedure. But nothing else needs to go.

On my '60 framed project bike you can get the tank off with the seat still on, you just have to compress the front edge of the seat foam carefully by hand. I'm using an Indian made tank, but I don't think your larger Redditch tank will cause any problems.

The front brackets for fitting the seat onto the mounting rail are a pain. I made life a lot easier by converting the holes in the bottom of the brackets to vertical slots!

Is that your big head Fireball engine in there?

Regards,

A.

The seat and rear guard assembly is designed to be quickly detachable, so can easily be removed as one unit and avoid the risk of damaging the tank.
Disconnect the wires to the rear lamp at the bullet connectors (if still original), then slacken off the top suspension mounting bolts and tap them inwards.
The complete "rear end" can then be lifted off.
