Whats the difference????

[N.O.S.guy]

I am just wondering if some of you guys and gals can help with something. How can you tell a Grayling made Bear Take-down riser from a Gainseville one? Are there some major things to look for or some minor little things? Thanks in advance for any help I can get on this subject.

There is a serial number cut off, but I do not know it.

I think the green stripe is also an indicator, but can't swear thats' 100% either.
