Coleman made dozens of different model lanterns over the years, but to me, this is their best!
In 1932 Coleman introduced their 1st single mantle lantern...the Coleman 242 "Junior" and was produced through 1935 when it was then replaced by the 242A, 242B and 242C series. The 242 was noticeably different by it's small vent and NRV which were phased out with later models. Here's one of mine dated April, 1932...the first year of production.
Here it is with a 242B...notice the size difference in the vents and the 242B has a PRV instead of a NRV...also the 242 has a straight globe and the 242B as a bulged globe.
Both these lanterns are in near mint shape...I've fired them up once and that's it...their shelf queens.
