MPC receiver question

I have a Sonora BBb 4v rotary horn ( a VMI/B&S stencil from the early '70s). I came across a posting on the TubaEuph group indicating that not all of these horns were manufactured with a real real mpc receiver, but instead just had a metal sleeve placed over the lead pipe.

So, three questions for the more technically adept folks on this board.

How do I determine if I have a "real" receiver on the horn?

If it turns out that my horn does not have a true reveiver, what is the level of difficulting of locating and installing a receiver on this horn?

If a new receiver is installed, what, if any, changes in playing characteristics would result?

Thanks for any info you can provide.
