AnaLog Services, Inc.
also has an extensive library of paper schematics and other technical documents. Included in our collection
is the entire historical original vellum / film schematic archive of Bell Petroleum Systems (formerly Worth Well
Surveys) comprising thousands of documents covering over a half century. We try to help anybody in need of
documents we have, but we must charge enough to cover our costs. However, we are always looking for schematics,
manuals, etc. not in our library; so if you have something we need, perhaps we can do some horse trading.
