p.1 #1 · mybackyardzone dot com seems to be a scam web retailer
I know you are all too intelligent to be taken in by this site, but hope posting reports about it here and elsewhere help take the scammer site down. Mybackyardzone lists lots of Leica lenses and accessories for sale. One such listing is "Leica 280mm f4 Apo Telyt-R 3659024" as being for sale, with multiple copies! But 3659024 is not the Leica product number for this old lens model. Leica part #s were 11261, 11263, and 11360 due to small changes over time. 3659024 is an actually a serial number of the lens made in 1994 per the Leica Wiki at L-Camera-Forum. I happened to buy the used lens with this serial number # from Camera West / Leicester Store San Francisco. "There can be only one," as they said in Highlander. Mybackyardzone's price is also hundreds of dollars too low for a decent used copy of this lens these days, much too good to be true. This site is almost certainly all fraud all the time!
