[Milsurplus] CV-157

[Reuben Popp]

Hey Nick,

So what you're really saying here is that for the quasi-experienced
technician it would most likely require some serious study as well as the
help of a more experienced elmer ;)?

I see that at least one manual (TM11-266) is available.  How difficult is
it to acquire parts?  Is it modular like the R-390As?  Just curious to see
if I'm potentially getting myself into deeper water than I care to wade at
this point.  Then again, I would hate to miss out on a piece of equipment
that others rate highly and I might be able to acquire at a decent price.

Thanks again
Reuben
