Incredible collection there! I love your Pelikans and your 51s.
I'm watching dozens of 51 sales on eBay. This one is ending the soonest. Watcha think?

I have no idea which ones are vacumatics or aeromatics. Neither do I know the difference... Apparently, Aeromatics are on the newer 51s so Aeromatic is probably better. I can't tell them apart.
I want to get a M400/420/425 too because my M600 is so good! M800 might be slightly too big.
