At least you don't see them around much. One with the big cover over the air valve is a 4500. Used only for a short time in 1911.
The other one is not a T carb, it is for an N R or S.
Nice. Early air cleaner / flame arrester on the NRS carb - wonder why they stopped that and waited twenty some more years until air cleaners became common on carbs? Maybe they got clogged easily?

I believe the screen was more or less to prevent anything from simply falling into the intake. I mean, if you were working on an N, and happened to drop a nut or bolt, you know exactly where it would go, right?
Thanks for sharing Stan.
