This is a 1965 H.N. White-era King 1240 in satin silver with a gold-wash 22" recording bell. Based on the serial number, this model is one of the last 1240s made in the H.N. White factory -- I believe the shift to Eastlake, OH happened in 1966.

This is a go-to summer band outdoor concert/Dixieland/Oktoberfest tuba. Great pitch, even with 3 valves. All slides and valves move very well.
Cosmetically, there are a few dents in the back throat of the recording bell, a few dents and dings as would be expected with almost 60 years of use, and the bell-to-receiver brace has been removed (but the leadpipe is securely soldered to the bell). There are also a replacement valve button and a replacement bell screw that are not original to the horn. Silver plate is about 98%.
That being said, it plays great.
Asking $800. Would prefer not to ship but can do so at buyer's sole risk and expense -- would likely have to do two boxes with the recording bell.
