HELP! MIRAPHONE 180 OWNERS PLEASE READ!

Post by the elephant »

I am in need of a few very careful measurements from the main tuning slide of a Miraphone 180 F tuba. (I don't need *any* other measurements from anything else; thanks, though.)


A — inside radius/span of the crook only
B — inside distance/span between the two outer MTS tubes
C — bore of inner MTS leg (if the tube end is not perfectly circular or is rounded in, then the bore size of the outer tubes)

For C, I am looking to confirm a measurement of .737"/18.77 mm bore of the inner tube (or .769"/19.54 mm bore of the outer tube), or a definite confirmation that this is NOT the case for either tube.

I need this info sort of soon, so I will cross-post this in hopes of an answer before January 10th. THANKS!
