I am selling all of my lay out which was 16' x 22', 85% of which is new, most in original boxes some purchased used. I never finished wiring the lay out, so a lot of items were never used. I will use C-10 for new items in unopened box, C-9 for new items that were on lay out but never wired or on shelf for display only, the remainder will be graded according to ware. My lay out was in a insulated and temperature controlled pole building with a dehumidifier.&n...bsp; This Item was purchased new for my lay out, and never used only on display. Unit 30-2114-1 battery was changed to a BCR red capacitor when purchased, was tested and placed on display shelf. Has been tested and runs and sounds great it dose have light dust .
