Need Help Holton 65 owners and experts

[dcslideman]

Hello all, trying to learn more about how my Holton 65 fits into the 65 history. From research here and elsewhere, I thought that there were two Holton 65 series. One ran in the 40's and another(the Buddy Morrow model) ran from the 50's until about 1965. The serial number on mine puts it at 1965 and it matches all of the observable and measurable specs in the original advertising pictures from 1957 attached below. BAsed on the 1957 advertising calling it "New" I thought 1957 started the new series. Recently talking to another forum member, he felt that my horn was a different iteration because the engraving was different and plainer. He also put an earlier date on the start of the Buddy Morrow design because he has a 1954 serial number which was played and signed by Buddy. He also thought that Buddy moved on to a different model(69?) at some point. Picture of my engraving also attached. So my questions are:

1. How long did the 1950's iteration that Buddy played continue? Was it the same until 1965?

2. Were there any changes to design after he stopped playing it?

3. Does anyone else have engraving similar to mine? What year serial number?

4. Any other Buddy Morrow 65 history tidbits are welcomed!

Any help appreciated! Thanks!
