Trump Brothers began making foot powered scroll saws in the early 1870’s with the introduction of the Fleetwood. It had an iron frame and was offered in several styles and sold for around $22. Later in the 1870’s, they introduced the Dexter which had wooden arms and sold in the $10 to $12 range. This was likely a marketing move as by that time other manufacturers were selling similar saws for less than $10 that for most people would do the same work.
Here is a copy of a catalog from the early 1870’s describing the benefits of the Fleetwood in glowing terms.
Here is the saw described in a J J Watrous Catalog from about 1879

Here is a yet to be restored version
The Dexter, shown in that same catalog was lighter in design and had a less fancy stand.

They also offered it in a unique but effective floor mounted foot powered unit as seen here.
