The Brand New Model F Keyboards project offers a bunch of the standard as well as custom legend keys including Mac icons, other icons, old style terminal keys, ergodox/hhkb front print styles, 4704 keys, IBM Model M SSK num pad front printed keys, and many other keys.

These will work on Model F and Model M keyboards, but not on Cherry MX or other type keyboards.  These key legends are far bolder and higher quality than many of the original Model M keys so they are not going to blend in perfectly.  Also they are all one piece keys.

Please review all of these keys at the Brand New Model F project's "New Custom Legend Keycaps and Extra Keys" page before letting me know which ones you'd like.  

The reason for the significantly higher price for this listing is to help cover the tens of thousands of dollars in project cost overruns for the Brand New Model F Keyboards project, which just passed $2 million in orders.

The pictured item is not the actual item you will receive as I have ordered many of these.  Please assume all items have cosmetic damage from the factory.  This in no way affects operation of the product.  Please note that this listing requires technical knowledge.  No support is offered by me.
