Looking for a mirror for a GRS XC signal light

[Erie Mainline]

I just received a decent GRS XC. However it arrived with a broken mirror. Are these easy to find, or does anyone make a decent substitute?

Do you have pictures of it? I never heard of am GRS XC light before.

The light is a General Railway Signal (GRS) type XC crossing signal light. Hope this helps.

is it flat? (looks flat in the pictures) if so maybe a glass shop could cut a new one for you. EDIT: definately not flat, where do you see the model. I just picked up 6 GRS lights that look like yours, one is pretty beat up but the mirror is fine, I have to check the rest but let me know if you are interested
