I've admired this kitchen too. According to the description, the sink was salvaged. - Rhoda

Yes, this is a salvaged sink - the overall width is four feet three inches and has two bowls.

It figures, everytime I find something I like, it's a one of a kind and I have to start all over again! Thanks for the response back from both of you, I didn't read any of the description, I got so excited when I saw it I fell in love.

These sinks come in single basin with integral drain board on left or right. They also come with double basin, the deep basin on left or right. They also came with no apron as shown or with 5 1/2" to 8" aprons.
They were available as described in 40-43", 50-53" and rare 60" single basin w/ single integral drain board. Beyond this style was a host of other styles, configurations, original colors etc. I would send anyone who emails me a SkyDrive album showing a variety of styles etc. Ken GrampasAntiqueKitchen.com

Additional response to the question of single basin availability.
The same style was made in single basin models form 24" to 42". The 24, 30, 36 inches being the most common. I have only seen one 42" single basin. Keep in mind that the single basins will all be only 5 1/2 to 6" deep! My apologies for not adding this comment earlier.
