Ricky style bridges?
 

So long story short I found a bridge rather similar to Rickenbacker bass bridges, it has the mute and everything. The only thing is, as far as I know...IT'S NOT A RICKY! It has a rounded bridge, but has the same general shape and the mute as the real ones, and it's a bit shorter as well. I was wondering if anyone could identify this for me, and maybe give some suggestions for how to anchor the saddle with some height adjusters, seeing as the only height adjusters I have at hand either have too small of posts, or two large of adjuster ends.
Thanks a bunch!
