Two aerometric Parker 51s and a Sheaffer PFM I. One of the 51s is in very nice shape, with a pristine rolled gold cap. The other cap, a lustraloy one, is in need of a polish.
I paid very little for the 51s, respectively 15 and 10 euros. On the other hand, I fear I might have overpaid the PFM, at 120 euros. It's my first PFM, though, and I always wanted one.
