So, after at least 6-10 auctions where I got overrun by rabid 51 bidders (is it me, or is this a trend now?), I figured I'd shift my sights a little to something more out of the way. The pen isn't here yet, but here's the eBay page.
Frankly, even I was surprised that no one else happened upon this or tried to snipe it, considering that right under the same seller, was a Lifetime Imperial VI with quite a bit more competition that ended with just enough time left for the curious to spill over to 'ink pen #2.' eBay competition aside, it looks to me like a decent shape Lifetime Imperial IV from the 60's. I'll update with better pictures whenever it gets here. In the meantime, time to find another Sheaffer converter.
