The Peerless[1] hooks look very specific to the width of the Peerless. What did the Albion hooks look like?
The Dennis hooks were mounted to the chassis, rather than the spring shackle (at least on the fire engines, possibly not on the subsidy trucks)

I would imagine it would be fairly easy to cast some hooks in iron that would look exactly right, if not necessarily perform to original specification.
(The chap in the above photo is a regular here, though I am not sure he has been espied that side of the lens before)
[1] Peer-less seems like a good name for an optician.
