What do you need…?...suppositories? 
Well…you’ve already stated the problem with your plan…
….it is extremely difficult to find any material on discontinued guitars and effects…
…so what makes you think it will be any easier for anyone else?
These days…if you can’t Google it…it probably doesn’t exist…or if it does, then someone doesn’t want you to have it.
You know…it may be easier/simpler if you post you some specific questions on these forums for specific gear that you are looking for….as there is a good chance someone may have that info for you…
…rather than expecting some “universal vintage gear catalog” to be assembled.
Just recently…some guy up in Canada must have Googling for info on a Fostex tape recorder…and he found some of my posts about that same recorder.
He emailed me directly…and I ended up photocopying the manual of the recorder, and sending it to him. 
So you gotta’ do a little leg work on your own…and there’s no guarantee that you will find what you are looking for.
