Hi,
I bought my Projector brand new from Professional Percussion in 1985, and I still have it. I should have some litrature somewhere detailing what was available but from memory the mk1 kit with the single lugs was available in normal and deep shells with either single or double headed toms. I do remember jazz or fusion kits with 18" kick drums and standard depth shells being available so this wasn't a special imho. the smaller sized kick drums still had the power depth and were marketed with a special name or tag line which i can't remember.
It was aimed at the serious drummer and sat beneath the Resonator in the product line. I can tell yours is an early one as you have the rubgy ball shapped tom holder, the mk2 had a round one and full length lugs on the shells. Your harware is original also.
value wise they're not worth a lot. I've been watching fleabay as I was going to sell mine recently and a five piece power sized kit went for £200. I contacted a few dealers and they advised selling the shells individualy as they don't sell well, people don't understand how good quality these kits are. I seem to remember paying £1500 for my kit with Paiste 2002 / Rude cymbals, and the prolok harware. I know i have the reciept somewhere, and I'll try to find it, but that would put the shell price at about £600 in 1985 prices I reckon. A Pearl export with budget hardware was £350 from memory so that gives you an idea of where Projectors sat in the marketplace.
They were available in Red, Black and White wraps or laquered wallnut, rosewood and clear finishes.
I think the drum shops made a kit up rather than the manufacturor so I don't think there was a standard snare that was supplied. Mine came with a 6.5" steel which I still have, I upgraded the snare soon after so it hasn't been out of it's case for 25 years. The same goes for the hardware, there were 3 levels, single braced budget, double braced and the professional level memory lock which I think was called prolok but i could be wrong.
The top of the range kick pedal at the time was the classic 252, I used one until I upgraded it to a pearl double pedal.
I remember choosing the shell pack and then the hardware in the shop. I'm happy to check anything against mine if you need me to.
The one thing I will say is that when I recorded with the kit on a few occaisions the engineers sampled it as they thought the tone was superb. I preffered the Premier DS heads as opposed to pin stripes but you won't find any DS's in regular sizes now. They are very well made, I don't think mine has pitted but i should check really.
And once again this is all from memory from 25 years ago so I could be wrong.
Hope that helps.
