This is the final model of the Keuffel & Esser Topographic levels. It was made in the 1960's and 1970's and ceased production in 1980 when the company was sold. The product number for this model is 80-0200. It is yellow painted brass housing and the only update from the previous type was the scale and bubble vial housing were now made out of plastic. Like the previous model, you could change the gradient scale around from percentage to degrees but now you could do it with thumbscrews instead of needing the pin tool. The bubble vial is a sealed clear plastic housing containing alcohol and is still accurate. It was sold in a green leather carry case with belt loop that you could attach to your belt.
