Tokheim announced their pumps by printing a Bulletin. The first mention of the new 850 is Bulletin #260 (First edition 1930). In it it states "Discharge Outlet: Cut 850 is equipped with but one discharge outlet. However, when the pump is placed on an island, gasoline can be delivered to either side. The discharge outlet is located 75 1/2" above the base of the pump."
Bulletin #260 (First edition 1931) for the "Improved" 850 states: Cut 850 ........... The outlet is located 71" above the base of the pump."
Bulletin #260 (Third edition 1932) for the "Improved" 850 states "71".
Bulletin #264 (First editon 1931) for the 850 Square states "working units identical to the 850 round." The picture shows the outlet and hose hanger on each side.
Bulletin #264 (Sixth edition, 1934) states the same but the picture shows the hose hanger and outlet on the same side.
Bulletin #270 (First edition, 1932) states the discharge to be 71" (both round and square).
All the 950 literatue shows the outlet and hose on the same side.
Many changes were made to the 850, see pages 276 and 277 of my book, there was also a change made in the skins and the reset handle of the 850/950 square version.
Copies of all the Bulletins mentioned above is listed on my website at: http://www.petrolianacollectibles.com/tokheim%20pumps.htm
No one has ever done a review of my book, but others have mentioned that would have liked to see more pictures in the ID book. I would too, the publisher limited me to 352 pages (same as the first book), I supplied 2000 pictures, they used 1900. There is also one more problem of showing pictures of restored pumps, who could afford to drive around the United States, just to take pictures of restored pumps? Pictures supplied by most restorers to me when I was writing the book were not suitable for publication, I like to say "You can't tell where the pumps stops and the Texaco sign starts" as collectors usually take pictures in front of everything they own.
One last thing about books for this hobby. I think I will go down in history as the person who wrote the last book that was printed. My opinion is that all future books will be on CDs and if you know enough about desktop publishing you can cut the CDs yourself and eliminate the printer. Or the book could be sold as a download and you just take your computer with you when you go out to seek pumps. The biggest thing the publishers provide is distribution.
