1930 Roadster Top Irons/Bows

[v8fordman]

Ok guys, I just bought my first Model A roadster from an estate and I need your help. I believe it to be a standard that was being made into a deluxe. The stanchions have been cut and lowered and the cowl light holes appear to have been drilled not stamped out. Anyway, it came with three different sets of top irons and two sets of bows. I think two of them are the same (the black ones w/ bows (pic 1) and the ones with the top attached [pic 2]). The ones on the far right (pic 3) would have to have the wood bow inserted into the top iron which is made of sheet metal. I am a pretty big guy and would like to have a standard (with more headroom). Can any of you help me determine, by the pictures, if any of these are standard or if they are all deluxes? Anyone know the dimensions of either or both. Your help is greatly appreciated.

While on the topic, does anyone have or know of any standard stanchions or perhaps some original deluxe ones if I don't have the correct standard top irons/bows?
