Kansas City area fire apparatus

[Guest]

hopefully someone on here can help me i recently purchased a 1976 Seagrave tiller model # PT20768 and the vin is E-76052. I have a feeling it was one of the group of four that were ordered for kansas city, it also has signs of the yellowish green paint they use to run (now painted white over red) just trying to track down the history of this wonderful rig its in outstanding shape. Any info or pics of it in service would be amazing
