Nakamichi RM-610 Remote unit for 610 Preamplifier Rack Set

I purchased the unit a few years back along with the Preamplifier.  My hopes was to slowly aquire the full rack set. Meanwhile my preamp has some issues and I haven't been able to track down the rest of the set. I know the remote is one of the harder pieces to aquire so I thought I had a leg up on the goal. Meanwhile I've aquire a lot of items like this that has left me hoarding audio vs running my business.  I know I have priced this a little higher than normal, but it also doesn't pop up too often so if there is someone needing it more than me then here it is. 
As photod it comes with the original box. This was the first time I have taken it out of the box to photo it. I am unsure how much it was used, but given the lack of marks or dust it is easy to conclude it was hardly used if at all. 
You will receive exactly what is photod.  Please send any questions and review photos before purchasing.
