<span style='color:brown'>I carry an atlas from Walmart called "The Roads of Oklahoma." I have worked in several states and Walmart has one for every state I have appraised in. It is published by Shearer Publishing, Fredricksburg TX. 1-800-458-3808
It lists Range and Township on section 1, it identifies section 6, 31, and 36. Section lines are on there so you can count to the correct section. It also has GPS grids, watersheds, and some topo information. It is (according to them) compiled from USGS maps, U S Forest Service Maps, and DOT maps. Face price is $16.95 and Walmarts price is around $13 or $14.</span>
I'ld either check with the county appraiser's office, or the registrar of deeds for the maps you are looking for. The zoning office may have what you need. Around here there are private companies that publish ownerhship maps which have the sec-twn-rng. Our county offices sell these maps or you can buy them from the publisher.
Our schedule number has the range and township included in the first five digits. Our MLS maps also include range and township. Check with your assessor, those maps are usually the best for that sort of thing.
