Mystery Trem with fine tuners

Found this on ebay.
I took a look though here and couldn't find this one, maybe someone knows what it is.

Description from the seller

"Unstamped and unmarked.  I've never seen a 4 string bass tremolo bridge before and this one is in great condition.  Has a metal base that mounts to the guitar and two indents which much sit within another part of the bridge (not included) to complete the tremolo function of this bridge (i.e. pivoting bridge).  3 of the 4 fine tuning screws are there.  Has 4 hex screws to adjust the distance of each string saddle.  4 brass string rollers for the use with the Tremolo system.  Nice overall condition, not sure if this is from the 60s, 70s, 80s or 90s.  I am guessing older.  I assume it is a chrome finish and not nickel based on the sheen but I could be wrong.  If you know what bass guitar this belongs to, feel free to share that information and I will update this posting."

 

Now....THAT....is TRIPPY!

Over the years, I have seen a very rare handful of strange bass trems that appears to be one-offs. It makes me wonder just how well they worked/work. I do know that the fine tuners are an issue, due to the massive tension of bass strings. So, part of me is wanting to try and grab this....yet experience quickly quells my enthusiasm. I've pulled the trigger on a couple of custom units that turned out to be train-wrecks.

We are still wanting to perfect our Kahler mods, but time has been a major issue.

Still, this IS an interesting piece! Great find, Al!

Hi !!
I am pretty sure that is an Ibanez guitarbridge...it is missing its frame.

Here it is

Wow good eye Hans!
Good thing you didn't pick this up Eric haha!

ACK! No kidding, Al! Thanks, Hans!   

saddle to saddle spacing looks narrow

those uuuuh rollers look like uuuuh kahler to me. so do the manifolds ... minus the screw in fine tuner doo dad part.

it does look like a bad experiment gone wrong.

that ibanez bridge looks nothing like it. sorry. it may be ibanez but it aint that.

You are absolutely right,Mike !! But i did some further research and found that that bridge is called Accutune.
