Above are the two sizes of grasscloth cases. The ones on the left in each picture are the bona fide 301 cases. Notice that it looks rectangular from the front, where the larger one is a more trapezoid shape. They have similar shapes when viewed from the side. The larger case is an aftermarket case that was sold by Singer for a number of machines. 301s are sometimes found with the larger case, but the smaller one is believed to have been sold with the portable machine. The darker color of the large one is due only to more soil and discoloration.
Above is the 301 case with a shortbed machine in it. There is always a little extra space to the side for the machine extras, but not all 301 cases have that metal divider. This case measures approximately 12 ¼” high by 17 ½” wide by 9 ½” deep at the bottom.
Compare how the case above fits to the one below:
You can see all the extra space around a 301 placed in the aftermarket case, about 3” extra in width and height. The depth is about the same. I’ve heard of many other machines found with this larger case….306, 191, 15, to name a few. The larger cases are often marked “Made in Canada” on the bottom, but the smaller 301 cases are not.
Cleaning tips: The grasscloth cases are dirt magnets and difficult to clean, IMO. I’ve tried a number of methods. I’ve had pretty good luck with Tuff Stuff aerosol FOAM cleaner (found in automotive departments…the trigger spray is good for lots of things, but I like the foam better for these cases). I let the foam work for a minute, then wipe with a soft rag, or use a soft toothbrush, gently, if needed. Too much scrubbing will rough up the grasscloth. Millie MacKenzie has had great results on hers using Lestoil and a damp sponge….I’ll try that on my next one! (Millie cautions: NEVER use the Lestoil on the machine, however…..It will RUIN the paint.)
