I bid on this auction with very blurry photos and a nondescript description, but thought I knew what I was bidding on. The description just said that they were a Parker 51 and a Parker 21. I thought the 21 was a Super because of the clip. I thought the 51 was a navy gray aerometric, but it turned out to be a little better than I thought. The first pen was a circa 1947 dove gray vacumatic Parker 51 with the stacked coin cap band and chrome plated clip. The second turned out to be a green Parker 21 Super. Both are in excellent condition, no scratches, no dents, great writers, just a little pitting to the chrome plating on the 51's clip. Not bad for $36.50. Every now and then you find a winner on eBay.

Oooooh....nice find!! Well done!

Good catch, Jon!
