Since the Blue Book does not mention the Guarantee Liquid Measure Co., and no production records have surfaced, it is hard to determone how many of each model were produced.

Only asking a question. How do we know the 177 was produced in larger numbers, when the 17 was produced for about 7 years longer than the 117?
