The value is pretty modest. That machine was made from around 1975 to 1980. It was the the 2nd machine down front the "top of the line." It is collectable to the right person but not exactly valuable since there are so many variables going into the value of a machine that could be nearly 40 years old. IF it still runs and doesn't leak, the value is, in my opinion, between $50 and $100. If there are mechanical problems it is worth less. If you can get more than that, good for you, but as a collector of these types of things I know I would't pay more than that.
