Solid wood (I believe it is oak) antique drafting table. On the front, it is marked K. and E Keuffel Esser Co., so it is the real thing. The marking of F-31 is also listed but I'm not sure what that stands for. As they say, "They don't make them like this anymore". It is in excellent condition.
Dimensions: 31"W (the main wood drafting part) with a bottom rail that measures 35" across. When it is at an angle, as shown in the photo, it is approximately 46" high.
$525
Note: Two T-Squares are available also (One is a K and E 24" for $45 and the other is unmarked 20" for $25
