I gave away my studio flashes about 8 years ago, so can't look for details.
I did not have brand specific radio triggers, all the cameras I had used the centre hot shoe pin to fire the flash, which was the only function I wanted them to do.
I then moved to "magic eye" triggers that used the flash from one light to trigger the others. (the big lights had that facility built in)
I also had quite a lot of flashes that looked like a large screw in light bulb for fill in, back drop lighting, hair lights etc.
It all worked well enough for me, but no doubt it would not suit the experts. One of my frustrations was the low ceilings in most UK houses. (and the lack of storage space for all the stands, softboxes, umbrellas reflectors etc)
The one thing I found essential mainly due to time saving was a Seconic L 308S meter, which I found in a box a few months back and now use for film, I had forgotten it was also an ordinary light meter
If I wanted to use anything again on a low budget, I think I would get one inexpensive studio flash, that could be triggered by another flash, with stand and accessories, some styrofoam and crumpled foam reflectors, and a couple of small flashes with light triggers, and build up from there.
My first set up consisted of car headlight bulbs mounted in baby milk tins, with various home made reflectors and diffusers. My ambitions hugely outstripped my apprentice pay, but I got results
