Keyboard functions perfectly after bolt-mod repair was performed (see included screenshot of the key-test program).
Modest dust-buildup was cleaned and the keys and keyboard case have been individually washed with care to preserve original labels. There are still minor black marks around the bottom sticker and very light scuffs to the plastic casing, but it's in great shape for a 33 year old piece of hardware. I've used this keyboard for over a decade with my older PS2-equipped computers that can't enter BIOS from USB keyboards. The keyboard originally came from a light-usage university environment.
In May 2019, this keyboard wasn't reliably registering the - key in the numeric 10pad. With the correct socket tools, it was discovered that some plastic rivets had broken due to age. The appropriate black M2 8 and 6mm machine screws, washers, and nuts were used for a partial Bolt-Mod refurbishment (24 of the ~60 total plastic rivets were replaced with appropriate machine screws). I gently pried on all accessible rivets and repaired every one that had broken or felt loose when plucked. These rivets are a common issue with the Model M and I will include a "supplies packet" of 40+ machine screws/nuts to provide the sale winner matching hardware to replace even the currently-unbroken plastic rivets should they choose (sockets/screwdriver-type tools not included).
I will ship USPS Priority Mail (buyers select a double-layer flat rate board game box or variably-priced larger box with additional padding). Local pickup is available too. I'm listing without returns due to the hazardous nature of shipping a heavy, older keyboard, but it is reliably working currently.
