This is dated inside- I don't know if this was typical. However that sort of date- month and year at that time was done by Montgomery Ward and my Wards 1642 is dated this way and this is dated as Jan 1938. The instrument looks okay from a quick glance although it shows many signs of wear and tear. Experts will be able to ascertain what level of instrument this one is in terms of build quality- it is sold as "refurbished".
