Query concerning T&NO dates

I know the T&NO was formally absorbed into the SP in 1961. Does anyone know how long after this freight stock still ran with T&NO markings?
I have some Athearn N Scale 3 bay hoppers with T&NO markings and numbers but also the SP herald. The Athearn website says that hoppers like these ran from the 60s to the 80s, Would these markings still have been valid thru that time?

Thanks for any thoughts on this!:thumb:

I don't know for sure, but I think they would be. Railroads usually don't repaint freight cars unless they rebuild them. Up until just recently I used to see gondolas in W.P. markings with U.P. reporting marks. I haven't seen any recently, so they may be nearing the end of their life.
