ScanDaBands;
I don't remember how/where I bought it. It is probably 20+ years old. AFAIK, the guy doesn't sell them anymore.
As far as performance, because of the greater spacing where the 'cones' meet the 'hat', results above 800 MHz are poorer than the top Discone.
Before you ask, it's not from RS or the one Icom sells, I don't remember where I got it, as I have had that over 15 years also.

Regarding the desks (there are two, the other is partially visible) I used the base cabinets from your standard 5 drawer metal office desk, removed the top and back panel, used 3/4" plywood for the top with framework underneath to fit in the room in two 'L' shapes. The 1st version I (unfortunately) used some plywood I already had. Not the best and I wished I hadn't. The 2nd version, I used birch plywood. Not as cheap, but surely worth it. I also used better edge/corner pieces instead of what I had left over from some RTA furniture as I used for the first desk.
That door leads to the Dinning room. The room was probably used as a 'den' back in 1917. This is a upper 'flat'. The lower doesn't have the door.
For those who have a 'keen' eye, that is a "Kill-A-Watt" under the calender.
