Info about the MW 2155R?

[That1TubaGuy]

So I have recently acquired a 2155R and am very curious to find more information about this particular model. I've been enjoying it so far, huge sound with lots of core and depth with the amazing Meinl 5/4 response I love so much. It piqued my interest because it looks inspired, at least somewhat--- by the Conn tuba that Warren Deck used throughout the 80s, the sound of which I have become obsessed with.

From what little is available online, it seems to be very rare (I guess I have a thing for rare horns) and according to the serial number (CF-101 etched on the valve) mine may be one of if not the first made.

If anyone here knows more about this particular model, I would gladly appreciate it!
