BTW, I think it interesting that several of these webpages show the
same parts with the same pictures in the same order, and the same
number of total parts for my model, 261. They must be all one company,
or they all buy the software and esp. the data from the same supplier.

Kitchen table "businesses" that buy a pre-made website and product line,
then try to get their own branded site to the top of google somehow.
They don't buy, stock, or ship, just take orders and get a commission.
