Unfotunately Ampex is out of business so they no longer issue "gold reel" awards... which were 1/2" reels on a black platic background with a plaque.
If you really want one I'll be happy to sell you one of mine.
The only 3" tape machine was made by MCI. It was a 3" 32 track machine that I don't believe ever got out of the prototype phase. The coolest part of that machine was that it ran at 20 ips which gave you 80% of the noise benefit of running at 30 ips with about 80% of the low end benefit of running at 15 ips and required significantly less EQ than either of the other formats... unfortunately the standard never took hold though you can get close if you take an AC motor machine [like a Studer J-37] and run it on its 15 ips setting on 60Hz US power [which brings it up to like 22 ips or something around that].
