There are actually two distinct variations of this first generation model...
The lantern on the left we'll call the [H1BF]. The one on the right is a regular [H1]. Note that the [H1BF] has a clip attached to the base.
The [H1BF] opens at the base. The globe is secured to a device that stays in the dome, but can be removed. Less than 150 of these were made when it was discovered that the device holding the globe was too secure - the glass globe couldn't expand/contract at all when necessary due to heating/cooling and would break. (This may have been more of a function of varying inside diameters as shown on the GLOBE page.)
The [H1] on the other hand is very similar to a Dietz Traffic Gard ... Only the dome opens.
Both variations fully disassembled with the burner absent and globe removed.
The above type was produced up to 1957. Discontinued when it was found that the bottom tank seam would develop leaks upon impact. As a result this variation was introduced:
The 2nd generation lantern height is the same as a Dietz Model 40 however in this variation the base diameter is smaller. It uses a #2 slip-fit burner with a 1/4" wick and appears interchangeable with the Dietz #40 burner. The globe part number was 58. Production continued until the St . Louis plant was closed on April Fools Day, 1964.
Any catalog sheet or advertising item on this lantern would be appreciated!
