Re: amosguy's comment about the diamond-shaped mounting plate on the tom, a look through Dennis J. Brown's "History of the Kent Drum Company" shows that Kent used several different tom mounts, including the old-fashioned type that clamped onto the bass drum hoop. And this type mount used the diamond-shaped mounting plate on the tom. I suspect this was the original configuration with the Kent kit on ebay.
The Kent book also shows the standard rail-consollete mount, but I never saw any of those on Kents.
I grew up near the Kent factory and nearly all of my drummer friends could only afford Kents. The only mount that I remember - from the mid-1960s - was the simple elbow-shaped mount with the ratcheting adjustment at the "elbow." The stem at either end fit into a socket in the bass drum and tom (same as the cymbal stem socket on the ebay bass drum shown in the pics) and tightened with a drum key against a small bolt.
This was a poor design; difficult to get your tom at the right height (if you were tall) and at the right angle and position, but for fledgling young drummers, it did the job. And that's all that Kent drums were - entry level drums at affordable prices.
About 10 years ago, I bought a nice looking 8-lug Kent snare on ebay, purely for nostalgic reasons. It appeared to be one of the better built Kent snares, but I was disappointed that it still sounded lousy! Ha! I sold it.
