Strange sight glass size gasket replacement

[uatuba]

Greetings! I’m getting back into the hobby after 4.5 years due to a move which took away my brewing space. As such, I purchased a load of equipment from a former home brewer. I’m cleaning everything metal and replacing everything non-metal.

One thing included was a 1.5” TC sight glass…but the glass itself is 1.75 inches. It needs a gasket with a 2” OD and 1.75” ID. Does anyone have any idea which manufacturer this is and where I could find a replacement gasket?

Your sight glass or diopter might be different, but have you googled them?

I did Google, but I think this will work. Thank you!
