Grant Stace makes a nice brass one, but when he does a run, they go fast.
Crosman makes the next best thing, and it is for their notched out breech.  It's the lpa mim.  this lpa is good for my aging eyes.
Shoot safely. Have fun.

I just like the classic look on some of my guns, I think I will get some made up over here in the UK.

 I received my Williams WGRS-54 rear sight and an extra fire sight aperture today.  It works perfect on my backpacker with a 760 fiber optic front sight.  I also tried it on my 1322 with Chavka sighted barrel band and it worked perfect on that one also.  The sight is very well made and seems to be exactly the right size for the Crosman steel breech.  The only slight problem is that the set screw goes into the dovetail notch and is a bit too short.  All I have to do is get a longer set screw next time I'm at the hardware store.

The firesight looks good on there.  Do you have a link for it?

Followed your link...that's the 70919 Fire Sight Ghost Ring Aperture $9.95 right?

When you get the longer set/grub screw can you please post the size?
Long days and pleasant nights to you...

Correct. Shipping was $3.95.  I saw this after I already ordered the sight from Midway.  If you need the sight and the extra aperture both it probably would be cost effective to order them both from the factory store.   I'll post the size when I get the screw.

I am liking that one  :-*

The mounting grub screw supplied by Williams with the WGRS-54 rear sight appears to be a 8-36 x 3/16(.1875)" cup point socket (headless) set screw (with a 5/64" Allen wrench socket). I haven't been able to find longer 8-36 set screws at my local hardware stores or gunsmiths.

It looks like what is needed is about an 8-36 x 9/32(.2812)" version of the same style screw, but I haven't been able to find that size listed anywhere online either, except apparently on some obscure Leica lens (fat chance...).

There are internet sources for 1/4 inch long screws, but it appears they'd be a little short on thread engagement in the sight body, and might strip when tightened securely. The next longer readily available size appears to be 5/16(.3125"), which is too long, and cup point screws are difficult to shorten properly (but not impossible).

Another possibility would be to fill the dovetail slot with a steel plug and use the original screw supplied by Williams.

Anybody have any other ideas?

The steel plug (or brass or aluminum or delrin) would be my choice.   It also protects the finish on the breech from getting marked by the screw.
