Hey Roger, You probably already found a bunch of these sites (Thanks Siu for the link to your site... I had not seen it before). This is the one I use regularly: http://home.worldonline.dk/rongsted/Rolleisn.htm If I'm going by sight (sometimes you just cant see the serial # on some auction listings), I use the rollei club site: http://www.rolleiclub.com/rollei/tlr/index.htm I guess you eventually get to know the different models by simply looking at them and the number of digits in the serial #... I'm far from there yet! Anyone for a game of guess the rollei by sight? No cheating! http://www.rolleiclub.com/rollei/tlr/images/012_Rolleiflex_2.jpg Peter (G.) [rollei_list] HELP! Rollei Serial No Source From: "Roger M. Wiser" <wiserr@xxxxxxxxxxx> To: <rollei_list@xxxxxxxxxxxxx> Date: Wed, 16 Feb 2005 18:57:27 -0600 I had the website that listed Rollei TLR models with serial number ranges and lost it. It would be most appreciated if someone could provide it. Thanks , Roger
