Model numbers are 60's and early 70's = 22,24,33,34,43,44,63c (centered) 63 (off set for 510's) 64, 83. The 3 is for 28 - 34 or 36 inch rows and the 4 means wide rows up to 40 or 42. I have all the books if you need the actual numbers. Model numbers for 70's and 80's and early 90's = 1133, 1134, 1143, 1144, 1163, 1164, 1183. later "Brazil" corn heads are the best. The snapping plates (as a rule) do not have a welded edge. Also there will be a sticker or plate that may have foreign writing (brazilianIJ) on the back of the head. Model n's for 90,s and up are 863 and 883. I am not familar with these later heads yet.
