Looking for a quick change style holder

Does anyone know who makes a small dovetail style tool holder?
Something like an Aloris quick change toolpost but not as big or
rigid. No need for it to have a quick change lever or whatever.
Just a simple pinch bolt arrangement would suffice. I want to use
something like this to hold some optical stuff on an XY stage.
Speed of removal isn't as important as repeatablility.

Actually all I'm looking for is a small block with a female
dovetail which can be bolted to an arm and something with a male
dovetail which will fit it. Like I said above, retention can be via
something simple like a pinch bolt.

Thanks,
Drew
