I work for a flooring company, and we have a sewing machine for binding the edges of carpet samples.
It's essentially a dedicated bias binding machine.
It's usually in the warehouse, but I had a chance to look at it today because it's in the office waiting to be sent out for servicing.
I thought I'd share, as it closely resembles a vintage domestic machine rather than an industrial model.
In fact, according to the website, they have been making this model for 25 years, so I guess it is vintage!
The casing appears to be all-metal. The motor is enclosed, but is mounted in a conspicuous bulge in the rear of the machine.
Looking at the machine, you can see that the design and materials are like those of our vintage machines, and very much unlike modern domestic sewing machines.
It's nice to see that, where power and performance really matter, vintage-style design values are still used.
If this machine was designed like modern plastic domestic sewing machines it wouldn't last a week, and nobody would buy it.
Here's a link to the website for this machine:

Make sure you're sitting down before looking at the price.
This price is probably not too different from the price of our vintage machines when they were new, if you take inflation into consideration.
Note also what appears to be a class 15 bobbin case, and the cutaway front which is presumably to allow for easy cleaning and bobbin changes.
It's quite possible that this is a specialized version of a regular sewing machine, perhaps made for them by a well-known sewing machine manufacturer.
Anybody recognize a family resemblance?
