[E. L. Moore noted on the Ceresota manuscript the cost of materials. Total cost in '75 = $2.85 US, which is about $11.15 US today*]
I was also fortunate in that there was a snapshot sized picture of the model in E. L. Moore's photo collection as well as a copy of the manuscript in the files. According to the manuscript, this is The Ceresota Method,
I guess I have a rather unorthodox way of keeping a record of time. I sit in my easy chair, pull up my TV work tray and play around a while. For an hour's work I put a dot on the calendar for that date (for half an hour, half a dot!), and for what seems like three hours, a blot. After that I hoist my feet up on a stool and pick up a book and call it a day. Union rules. When I've finished I count up the dots and blots, add a few for good measure and that's that.
I'll contact the National Institute of Standards and Technology.
* According to the cover letter to Russ Larson that accompanied the manuscript, a trip to the hospital to fix his knee cost far more than the model,
Coincidence: just finished reading Emergency Room by a hospital intern . . . now I know what the inside of an emergency room is like. Book only cost a buck, but a peek at the room cost me sixty bucks the hospital says. Out walking, sans glasses, sidewalk veered but I didn't. Nothing serious; a few stitches on the knee and a few minor abrasions. Main discomfort is brace that keeps from bending knee and pulling out stitches. Just try putting on your pants or a sock over a straight peg leg.
