Jonathon,
I was a regional and in house DD, for both Freds and A/M at one time or another.
A/M being the older of the 2, had that variation in both BR and Silver long before anyone else. ( my last dealings as a coach with A/M was in '03... it was still being taught then ), dont know about Freds current status .
Havent seen the DVIDA one, but from the description, it bears no likeness to the original .
