ID for what? They are indeed '32 roadster / phaeton windshield posts and brackes. They look to be chopped. Are the brackets polished br***? The color is not too clear on my computer. My guess is the electric pencil numbers might be a work order/ customer number from the shop that polished them.
Ah makes sense, electric pencil ,the bases do some age and discoloration . Yes I believe they are a 2” chop. Just my son commented on the nice quality of the pivots etc. he has seen some poor posts too in his hot rod fabrication job.
