Univac 3 video on youube - tape drives

I mentioned having a Univac 3 available for sale and have some interest. When I watched a video linked to by a person on the IBM-MAIN mailing list some time ago, there was a few Univac links, so I looked to see what was there for Univac 3 this turned up which is supposed to be the US Army system http://youtu.be/ICGPML5lzoY There are tape drives in the short bit of video which are not Uni-servo's and are probably not connected to the Univac near the end, but you can see the system's drives in one bit of the video. NOte that it had no disk storage it was all tape with the OS at the BOT of every volume, or bits of the application. Anyone recognize the logo on the tape drives (probably not Univac) at the 23 sec point? it is a big red circle with two side bars. Rings a bell to me but I haven't figured it out yet. There was also a CHM show about timesharing with Univac that came up, but I don't think the tape drives are the same Uniservo's that the U3 used, so is probably later. Also the theme is timesharing which of course the U3 was definitely not ever going to do. thanks Jim
