Wonder why Binder Bks. shows five different ones and what the difference is? Looks like there using the IH manual numbers with the R suffix off.
Manual 1004288 for serials 501 to 19233.
Manual 1004313, for 19234 to 22701. Can understand these being different, one is stage 1 and the other stage 2.
Manual 1004371, for 22702 to 26841. Only thing I can think of for this one is maybe it showes the later wide front and the others before this have the old type.
Manual 1004373, 26842 and higher. I have no idea why this would be different than the last manual.
