Norton's, a lot: Manx and International featherbed and gardengate frames!

I think you mean Nortons, not Norton's. Yes, a Manx in the foreground. The other #1 behind might be just post WW2? because it has tele forks.

Norton Manx. With that short megaphone exhaust it is a fairly late one - maybe 1954? Maybe even 1956.

This one is a Norton, a single cylinder model. Can't see enough to tell wherther it is an racing ohc Manx model or just a modified pushrod ohv road bike. It does look as though it has a proper racing fuel tank though.

(Let's make it a '1963', the last to be produced.)
