Looking in Nick Stroebel's Book "Old Gunsights,(1998) the Lyman 60 Extension Receiver Sight was last cataloged in 1974, but introduced in 1959.
The Lyman 60 is listed to be used for several Rifle Receivers, including Winchester,Remington, Savage, Anshutz like you have, and possibly others.
Values Listed back then, and I know from dealing with Collectors over the years, was used as a guide line, and starting point for pricing.
$75.00 Bucks
I don't think you can replace the whole sight for that $$, but if you only need the bent peep screw, and maybe another part you might get lucky.
If it was insured I think I'd try to push for more $$ if possible. Looks like the top bar stock metal that holds the peep is bent and another part that the peep sight screw goes into is missing.
Google Vintage Lyman 60 receiver sight, and you can get a better picture and see what I'm talking about, also click on various pics for additional info and or possibly finding what your looking for.
Like Bugger suggested you'll still be able to find parts as needed as there's guy's who specifically deal in sights at gun shows, and online.
Ebay also lists them,Worthpoint, etsy, I would even go on WACA forum as a guest and ask if anyone has one for sale.
Good Luck, I hope this helps,
