Help identifying a reel please

I need some help identifying a reel. I have had a Shimano Low Profile Baitcaster for some time (15 to 20 years or so). It has some distinguishing features – it has a switch that changes the Thumb Button to a Flipping Button. That is if you push the button, the reel is free but as soon as you let it go it stops. It also has a switch that lets the reel free spool on top of the reel. I am hoping to find some data on how to take it apart and clean it and how to best adjust it for casting (I have been using it to troll).

Thanks

I think it is a Shamino Coriolis, I have one that is about 20 years old, I use it for flipping. It is one of my favorite reels, last year I had to have a local guy go through it and repair it, now it is as good as new.
