Looks like a rear mudguard for 1960 on A7 and A10.

As Julian says It's a swinging arm model A7/10, judging by the holes in it.

Thanks for the replies
Would this be a good fitment for the 1958 super rocket? There are no holes in the top of the guard for the seat bracket.

The 1958 mudguard was different with different stays. The one in the picture takes L shaped dual seat brackets which fit on the side.

The mudguards in the photo are from a 1958 Super Rocket.
