Well, there were a lot of different companies out there making boxes. I've not seen the one you show, so I'm guessing that it's more modern than those I'm most familiar with. Such things show up on the internet auction and sale sites pretty regularly, so I think that there's a good chance that you'll be able to find one. Annie

My mother was given a family sewing machine from my father's side of the family. Lore has it that a great aunt sewed a vest for Tom Thumb on it. This man was a circus performer. My father was born in the 1890s, so our Singer was pretty old too. It had a very nice wood box and cabinet on decorative cast iron legs. I learned to sew on this Singer treadle machine and preferred it to the electric ones because it was so easy to control.

There are other manufacturers you may want to check out, particularly Kenmore mady by Janome, Brother, and some of the White brand machines (one is on sale for $199 at Joanns and is a decent machine..recommended it to my cousin who has the same wants as you as a highly-advanced, fabric-fearless sewer). I also have Singer machines and never have had a problem with them. You cannot always go by price, go by the features you want like my cousin is doing and then try them out at the dealers so you find the machine you feel comfortable using.

If your machine is running slow it could be that the foot control needs servicing or replacing or that the carbon brushes on the motor are worn and in need of replacing. Replacing carbon brushes is not unusual and I have done it myself with different motors, including my Bernina. A new foot control will run somewhere about $30 and the brushes should be about $15. The brushes are easy enough to change yourself if you are at all inclined to do such. I order from an online source. I would shy away from any modern Singer and look to some of the others makes. Singer has allowed that name to be slapped on many totally unworthy machines. It carries a lot marketing weight. The old Singers from way back when were good machines. That is no longer true. Keep it simple with a mechanical model. That is the only way I roll anymore. Why complicate life? I seriously doubt that many people even use the decorative stitches on their machine very often,whether the machine is mechanical or computerized.. After a lifetime of sewing I know that I have seldom employed that feature on any machine that I have used. I have never found them to be very attractive or useful. Good solid function is the best thing to have. . Good luck. It has become difficult to buy some things right now. If you like your machine and dont really want a new one, you might consider the possibility that it is one of those factors that is causing it to run sluggish. Both are relatively inexpensive to fix. You can always buy and try a new foot control. If you are not mechanically inclined you might not want to change the brushes yourself. It is not difficult but can seem to be daunting if you are not of that mind. Vacuums also have these carbon brushes as do power hand tools and fan motors. Have you noticed any black dust around the motor on your machine, or any sparking around the motor? That is an indication that the carbon brushes are wearing down. It looks like the motor is behind those little vents on the inside of your sewing area. Oiling won't help with either of those problems. It is likely sluggish because it is not getting enough power to turn the motor. If something were preventing the hand wheel from turning or a belt was loose, that would be obvious. It sounds as if the motor is not getting the power it needs and is very likely to be either the carbon brushes or the controller. Of course it could be the capacitor on the motor, but that is also easy to change. Parts are not terribly difficult to find. The expensive part is usually the time and labor. You are paying for the knowledge and experience and the tool belt of the service person, as expected if you employ them to fix it.
