Cat D7G and D9H

There were several D7Gs made here in USA & over seas but the 91V USA came out in 1975 & the 72W in 1976 & the D9H 90V came out in 1974 & there were other SNs too in the D9H & it looks like the D9L 14Y came out in 1980.The 5BF D7H came out in 1987 but as I mentioned the 7Gs were made in a few countries besides USA so maybe this will give you a little idea.

Thanks OM and SJ. That is what I needed and I really appreciate it. 😊
