Re: When did Duncan start putting logos on pups?
My most recent pup without a logo is a zebra DD purchased in 1986. It was ordered from SD. That DD was a replacement for a black JB I purchased in 1985 that was very similar to the one you describe. My JB was logo-less also. Although, I can't remember if the JB was sitting in my dealer's stock or had to be ordered from SD. I didn't buy any more pups until ~1996 and they had logos.
