Kluson style tuners

Having a bit of a clear out,and came across these tuners...can`t remember where I got them from, but they are Kluson STYLE tuners, look old,but they might have been relic`d at some point...they really look the part though!They are Japanese,I know this as they have "Japan" stamped on the back!..the buttons are actually very attractive,and they appear to work fine,and seem to be of pretty good quality.
There aren`t any bushings or screws,but they are easy enough to get. The shafts measure 6mm, (by my tape measure!)
N.B....the keys are a bit more "creamy coloured than in the pics.
Thanks for looking.
