The Singer model 301 had two types of bed extensions -- a short one and a long one. I am not sure if they were available in all color combinations - probably so. I had a black long-bed and now have an all tan long-bed in a carrying case somewhere in my basement.

P.S. I took some photos of quilts on display at the AQS in Lancaster, PA. When I get them over to my WebShots page I will post a note/link to them here. There were plenty of amazing quilts there.
