Buses from Ribble & Crosville depots on Merseyside had similar arrangements, were buses carried both Merseyside PTE & NBC logos, but had NBC corporate Red/Green livery.
Another thing, Earlestown & Newton Le Willows has been in Merseyside, & Merseyside PTE/Merseytravel area since the county boundary changes in 1974, had an amusing situation in the early 80s until deregulation, were the routes & buses were provided by another PTE (GMPTE), this situation came about as historically buses & routes in the Town were operated by Lancashire United (LUT) as the Town was well outside the St Helens corporation area, but LUT were bought by GMPTE in the mid 70s however LUT were kept independent until 1981 when GMPTE merged LUT into GMPTE, thus the situation in Earlestown & Newton Le Willows.
