The placement of that tom mount receiver on the bass drum makes me believe the set you're considering was originally configured as a Top Hat set like the 1966 Top Hat set that I own. The drum sizes are 14x20 bass, 16x16 floor tom, two 8x12 toms. I would love to have a matching Luxor snare drum. I think that Bob is correct in saying that the tom mount on the set you're considering looks like an Asian knock-off of a Roger Swivomatic mount.

It is an Asian knockoff. Look closely. You see these tom holders on 70's Tempro drums and other MIJ brands. That alone is a bargaining chip.

That bargaining chip is worth at least $100. If I were to buy that drum set, I'd replace the tom mount with a Swivo cymbal mount. Then, I'd install a proper Swivo tom arm receiver at the drummer's eleven o'clock position closer to the batter head and get the proper hex arm tom mount for the 8x12.

So, you would make an extra hole, not too wise.

You bet your bippy that I would. Once again we disagree. If anything, the added mount would add value to the drum set. If done properly, who would even know that Swivo and Knobby mounts have not been on the drum since it was brand new? This is one of the great things about Swivo era drums.

Well for one you would know and if you tried to sell, you'd have to disclose it or you'd be deceiving a potential buyer.

Of course, I'd point out every change to the drums that had been made. You should be aware that many drum sets arrived to music stores back in the 1960's--especially drum shops--without various hardware mounts, supports, and legs. The selling dealer would configure those items to the new owner's specifications. Would those be considered modified drums? Should they have been sold as unoriginal to the first owner and any subsequent owners?

Not if it was done before the kit was initially sold. Anyway, I have no issues with modified kits if it's done right, however I know there are some who do.

We're having disagreements over choices of words. Let's say that I went to Lou's Drum Shop in 1966 to order Silver Sparkle Rogers drums. I decided that I wanted a 14x20 Holiday bass drum, an 8x12 Holiday tom, a 16x16 Holiday floor tom, and a matching Silver Sparkle Dynasonic snare drum. I wanted the drums delivered with no mounting hardware or spurs on the bass drum, Swivomatic receivers and collet on the 8x12, and Knobby leg mounts on the floor tom. When Lou called to tell me that my new Rogers drums had arrived, He asked about what mounts I wanted on the bass drum. I told him that I want two sets of Swivo spurs on the bass drum, a Swivo tom mount at the eleven o'clock position centered between the front and back heads. I also decided to have a Swivo mount added to the eleven o'clock position on the bass drum between the two lugs nearest the batter side and two Swivo disappearing cymbal mounts with tilters in the Buddy Rich preferred positions. This would also require adding a Swivo mount to the snare drum placed at 90 degrees spacing from the throw-off and the snare butt. OK. The drum set was already sold to me and Lou's Drum Shop were professionals at this sort of thing. Is my new drum set considered modified or original? If I sell or trade in this drum set in the future, am I obligated to relate this entire scenario to a prospective buyer or drum trader?

Ok, I can see you like to argue, when a kit came from a music store back in the 60's and was bought new, I would say no. But if those mods were made after 40 plus years, yes.
