"All over the map" might be a gross understatement. How about a Reso-Tone 2 with standard offset trill keys?

If they only ran 1 serial number sequence at a time, the one I posted would have to be pre-1968. Based on the production numbers of the official serial number list, I calculated it back to late 1967, if they started with A00001.
Numbers in
red are based on them going to 99999 before changing prefix letter, The
Blue numbers I can't figure. To run to 99999 before switching would have both those years over 80,000 units. D in 1983 probably went to somewhere in the 37,000 neighborhood before switching to E. 1984, E could have gone to around 30,000 before switching. Hard to determine as the next 2 years '85 and '86 put up the lowest production numbers. The last 4 years are an approximate based on them starting at A00001. This 35 year sequence accounts for over 800,000 Vito clarinets.

mechanic, that looks like Lisa's '74 Vito on page 1. Her copy seems to have the normal LH pinky keys. These Vito's are "all over the map" in terms of logos, models and some features.
I'll post about my Vito, serial number B22750, manufacture date of 1974.
Its not specifically labeled as a resonite, but it's not wood. It is marked only with "Vito" on the upper joint and bell, and matching serial numbers on both upper and lower joints. School inventory number WSD 74-132 is scratched into each piece, except the mouthpiece. The Vito mouthpiece pictured is my own, not the Encore one it came with. I can't find any info, other than the serial numbers put it at 1974. I've not found one picture like it, none. The knurled metal joint rings-bands make it distictive. Other forum members were sure it was wood, based on pictures, but it isn't, so maybe a prototype?
I think it plays very nicely and easily, I really like it a lot, and am not bothered that it isn't wood. I hope a lot of kids played it, and got a good start on clarinet. For a school instrument, with 74 scratched into it, telling me it was added to the fleet in 1974, and in my mind, verifying 1974 as a manufacture date, it's in fantastic condition, so I think it was appreciated by its players.
