Congratulations 
I had two surgeries and a tooth infection that resulted in a lower partial. I still work on it each day. I found posting youtube vids helped me a little. I had something to work toward. I find I must use a very slight mouthpiece placement change.
I'll sound Taps on our courthouse lawn by the vet monuments. Last year it from our front porch.
Use "Corrosion Cracker". I watched a tech use it to loosen a stuck slide on my Schilke and have kept some around ever since.
I can see two finger rings around the third valve side. It may just be the photo angle, but the valve bloc looks positioned more to the back than usual.
I recall when beginner instruments had no first valve thumb saddle, and the third valve slide always had an adjustable throw ring that could be removed for a lyre.
@dr-go said in Played high school trumpet:
What I most loved about high school band... is dating clarinet players. That's what REALLY developed my embouchure.
Yeah. I married one
I practice some each day and made short videos of me Christmas carol playing around town and on friends' lawns. I also visited some historical sites/cemeteries and played hymns. I'll continue that soon. It has been good to put myself under a bit of performance pressure because I am still recovering from surgery and a dental procedure.
Been playing a few hours?? Buzz the mouthpiece five minutes on the easiest pitch for you, take a break, do it again. Take a break then play a few long tones on low C and D. Stay relaxed. Add low B and Bb or Eb when you feel like it. Repeat that everyday for a few days. Do a couple of sessions per day.
I have developed the quadrangle so we can give up the triangle and still enjoy the 'ding'.
HA! Choleric for me. I've never had cholera in my life 
It has removed the smell of musicians who formerly played on it!!!
I use: Al Cass, Blue Juice...I used straight kerosene while in college. Dad had a service station with a kerosene pump.
Very enjoyable! I had not seen those pictures of his younger days. Thanks
Dr. Downing, 26th NC Regt. Band, sent me several of that group's recordings several years ago. I discovered "Butcher's and Drover's March" in a museum here in Arkansas and provided it to him. The band's arranger produced a band arrangement from the piano score and the 6th performed it. The march was from 1860's Philadelphia and composed by the first black band leader in the city. I believe his name was Johnson. I ran the Ark. 5th Regt. Band for a few years. We played in 4 states and performed for the national SCV convention. Never could afford replica instruments, but the Robb Stewart horns looked great.
@Bob-Pixley Sad, sad news. His recording of the Hummel is the one I prefer.
That "Russian Sailor's Dance" in the encores section was very fine
