I own a 66 marshall 8x10
If it has pinstripe, with leather handles on the side, It's a 1966-67 Era marshall cabinet, cool thing about that era of cabinets, is that jim Marshall himself made these cabinets himself, tolexing and stuff, this was the time before people had to put there names inside to see who the builder was, incase there was a mistake and they needed to know who built it, put up pictures and i can give you a rough adea about what year it is.
