Hi Raid,
I don't know who that Frank character is, but I wasn't joking. Anybody can get a Noctilux or a Full-frame-Extra-extra-low-noise-Image-stabilized-custom-programmed-thing-a-ma-giggy, but who can say they have a lens from Master craftsman B. Sweeney? We're collectors! No one has to know that yours was less modified than the Nikon ones....I mean, I don't know if it was......Anyways, your lens is rare and it works great. Too bad about the super rare lens cloth though......😉
