Where to get porcelain kitchen sink+drainboard combination?

Does anyone know of a company that's reproducing the cast-iron, porcelain-enameled sinks with drainboards as featured on top of this metal sink base? They were very popular in the '50s and while you can get them today in metal, I cannot find a source in porcelain.

They can be picked up salvaged -- such as this one at
www.historichouseparts.com. But it seems like they could also be easily reproduced. Let me know if you have a source and I will feature it on the blog.

Kitchen sinks: Great 50s style choices

It's Mac to the rescue again with some nice choices of cast iron porcelain-enameled sinks for the kitchen. The first two sinks pictured are both from Mac the Antique Plumber, http://www.antiqueplumber.com/, and the site says the same same supplier has been making them for 70 years. I believe them. I salvaged four (yes, four) similar sinks circa 1963 recently, and will install one in my upcoming kitchen reno.

The stainless countertop sinks are both from Elkay. I recently saw the first one in an ad from the 50s - it appears to be virtually unchanged from then.

Blogger not letting me post my final pic, so I will have to do a separate post of the sink I REALLY want to see reproduced: A cast iron porcelain-enamal sink/counter combo like the stainless version from Elkay above. IS ANYONE MAKING THESE?
