> Unless the power connector was phyically altered to a different type as part of the modification, this franken-R-648 could easily be installed by error in places where the normal R-648 should have been.  That's to be discouraged in the US military services!

But you know that it has happened...

> There would have to be some sort of official documentation of the modification in the system literature,

Yes, there probably is a special TO or manual on it - but if the
modification was not common (apparently very few were done, from the
examples seen today), few manuals would have been printed. Perhaps one
will show up someday. Or not. If only 500 mauals were printed in 1955
or so, what are the chances of obtaining one today?

> and at the very least some obvious visible indication of the modification present on the unit to keep it away from places it couldn't go anymore.

There should be, but perhaps not. If so few were modified, for some
specific project, perhaps they did not bother.
