I ran across these forums as I was looking up information on these desks. I first came across them about 15 years ago and I have really liked them ever since. I am now looking to fill my home office with these old "mid-century", "tanker" pieces.
General Fireproofing is my favorite maker. Followed closely by McDowell and Craig. I recently picked up one of the 60 x 30 McDowell and Craig tables (actually a desk with no pedestals). It is in nearly perfect condition with nothing more than a couple of areas where it appears that the table came up against something that took the paint off of it. Nothing major, though. With the price all over the place on these things I was happy to find this one for 75 dollars.
Eventually, I want to get a 68 x 34 desk, 68 x 34 "table", a drafting table, a credenza, a side table, two of the 36 x 24 tables and a couple of the book shelves for my home office. I have yet to really decide if I want to try to find them in excellent original condition, or if I will have them re-done. I live pretty near two of the big refurbishers (Retro Office is the nearest). I think that I can gather enough of these desks in good-enough condition to sharply drop the cost of refurbishment. If anyone has any good intel on General Fireproofing pieces in SoCal, any info would be greatly appreciated.
