The display filters are often discoloured - no idea why, but perhaps UV is part of the problem. Some are fine. Perhaps where they are used and stored is a factor. I doubt NOS filters are available any more. I did find a couple in a drawer at work, but have fitted them to the scopes we still have in use.
A word of warning - I wouldn't try to change it unless you really have to. Philips used a type of plastic that often goes brittle with age, and the act of pulling the bezel from the front panel to access the filter might cause the lugs to snap.
Personally, I think that £120 is well over the top, but having just taken a look at the sold prices of Philips test gear on eBay, it appears that my collection is worth much more than I realised! Well, I've always said they make good test gear, and the current sold prices seem to reflect that. Is this one yours? https://www.ebay.co.uk/itm/Vintage-Phili...3642536023
