Hi! Strange as it may seem
you can find free manuals for 19th century White brand sewing machines via the Singer website.
Look under Singer's "Support and Resouces" then select "Instruction manuals" , or
follow this link:
http://www.singerco.com/support/instruction-manuals
On the Instructions Manual page you'll see it says "Find Your Manual - Step 1, Step 2 etc etc" and under that there's a search box that says "Model Number"
Into this search box just type "w"
(don't type "white", because that doesn't work)
You'll be taken to a near incomprehensible results page and unfortunately
the method to finding the manual you need is a case of clicking and opening the PDF manuals.
However may I suggest a couple that may be of use:
"
W7treadle"
- this is a manual of White treadle with a "boat" style bobbin shuttle
"
WRotary"
- this is a manual of White treadle with a "rotary" style bobbin shuttle
Good luck, and I hope you find what you need :)
Kind regards
Kura
