Nice decks!! Nice youtube video!!
At one time, I had a VTR/VCR that was a transition between R-R and cassette machines. As I recall it was a National. The tape was contained in a small cassette with only ONE reel inside... when it was loaded the machine would thread itself around the heads and to take up reel (5"?)contained under the top cover of the deck. It was color. Do any of yours load that way?

It was more fun to watch the thing thread itself than the ONE cassette that I had.
