Good deal for canada. I posted about this on IRC when it was listed earlier.
Someone asked me about this KB, and fortunately I was able to ID it based on another ebay listing.
Production date was in 1983 or so, so it has the "modern" style HE switches. I believe most were PN: 4B3E
4: blacks stem
B: angled stem
3: "normal" weight
E: 3 pins
Though there are some others.
