Look closer on the trigger, I think you will see that that is LT-Q, which would be Quality Hardware. As for the E on the housing - I dont know, probably an inspectors mark. Look on the left and right side at rear sides by the rear lug and see if you see a marking, or on the back of the magazine well. Underwood puts .U. in the magazine well.

Hi Rustship, here is another mark that I found on the right side, seems to be a sideways U, is that for Underwood? TIA guys...
