Hello,
I think I read somewhere that some of the lightbridge series used GSO mirrors for a while. I see you have some writing on the side of the mirror, can you read any of it?
You can get a F5 250mm from a GSO mirror supplier that would suit your scope perfectly. You can get a new primary and secondary for around $380(plus postage). As long as the are "diffraction limited" as sold by GSO you'll be fine.

Ps. The current surface needs to be removed prior to a recoat, and that is not always successful. I'd be worried that the mirror maybe be too far gone for a recoat. A mirror surface should be down to single digit microns when polished and ready for coating.
