Conn 79H Elkhart engraving?

[Mamaposaune]

I'm wondering if the Conn 79H's from the late 60's were engraved Elkhart Ind? Hoping someone here owns one, and could check.
(Early 70's ones were engraved Made in USA)

My 1970 (N series) Conn 79H

Again, thanks. Since Conn only made the 79H between 1966 and 1971 (according to the Conn Loyalist) it seems likely that the ones marked "Made in USA" were made in Elkhart, although possibly assembled and engraved in Abilene. Just seems unlikely that they would set up tooling in TX for only a short run.
The 79H also has the same size rotor valve as the 88H. I'm in the thinking stage of selling mine and just sticking with my Bachs, which I have a slight preference for, but have noticed that the 79 is more open on the trigger notes below the staff than my 36B and 42B, which also share the same size rotor.
Here's a revelation to me - based on the rotor caps, all 4 horns have the same size rotor!

There were Elkhart made instruments that were engraved "Made In USA".
