I was wondering if anyone could explain the rareness of this complete set found in the 1971 catalog. The set includes exactly what the catalog displays along with the 14" super-sensitive 410 instead of the 13". Original cases are in decent shape and overall shells are great. Heads need cleaned but I could not believe I have an original set!! It was purchased for my father as a wedding gift from my grandparents. I thought it was a mix and match set until I found out it is this rare original kit. Someone please help direct me in what to do with this set!! Help2
