I've got a couple dozen pieces of original 65-68 glass here and none had that small logo. I thought maybe it was changed or something, but then checked late '68 glass and they all have the larger logo.
The company wasn't OEM Auto Glass or ECS, so I'll leave it at that. The company agreed to re-apply the stencils, but they want me to pay for shipping both ways($200 each way). Not a way to treat a customer for your own mistake. Like I told them, just because the standards of other customers are low does not mean I have to change my standards.
