The MSRP C-III states that 104 tanks were insulated carbon steel low pressure tanks with 2% minimum expansion dome.

103's could be insulated or non-insulated with 1% or 2% expansion domes with or without bottom outlets depending on the construction material.

No one has ever explained to me why a 104 couldn't just as well
be called an insulated 103. They made 103's with big domes and
safety valves, didn't they? Now someone is asking about a 104
built for 300psi? Doesn't that make it a 105??
Sunshine had a Warren 104 kit -- a car built to carry "natural"

No, that is not exactly correct. The 104 is more like an insulated 103 made
for specific commodities like ethyl ether, casinghead gas and refine veg
oils, and has a 2% dome with safety valves on its (usually very large)
insulated dome, while the 105 had insulation, but had a top unloading valve
casing with no bottom outlets, for pressurized commodities, if I remember
right. AHM used to make a late (1955+?) model of an ICC 105A300, that I have
a couple of, but I have never seen a model of a 104.
