I am still glad some of you are interested in this subject (although I imagine many are yawning off at this point), and having finished with pretty much the remainder of 103's, here goes part 3, the 104's and 105's:

ICC 104/104-W (obsoleted 1964): Ethyl Ether; Casinghead Gasoline, Refined Vegetable Oils
Steel Riveted or Fusion-Welded
Insulated
2% Dome
Safety Valves (35 psi) or Safety Vent (45 psi)

104's were not all that common, as they were made for some pretty specific commodities at a time when tank cars were evolving quickly. I don't know of any specific models of them, but there are some insulated 2% dome cars that one could modify, if one wanted to.

ICC105A100/100-W (obsolete 12/19/64): Ethylene Oxide; Liquified Petroleum Gas (V.P. not Exceeding 75 psi @ 105 deg. F); Liquified Hydrocarbon Gas (V.P. not Exceeding 75 psi @ 105 deg.F)
Steel Riveted or Fusion-Welded with Manway Nozzle
Insulated
Top Unloading Arrangement Required
Safety Valve (75 psi)
Bottom Outlet Prohibited
Bottom Washout Prohibited

ICC 105A200-F, ICC 105A200-W: Sulfur Dioxide, Vinyl Chloride, Liquefied Petroleum Gas
Converted Higher Pressure Forge-Welded or Fusion-Welded Tank
Steel Forge-Welded Tank with Manway Nozzle
Insulated
Top Unloading Arrangement Required
Safety Valve (150 psi)
Bottom Outlet Prohibited
Bottom Washout Prohibited

ICC 105A300, (obsolete 8/31/56), ICC 105A300-W, ICC 105A400, ICC 105A400-W: Anhydrous Hydrofluoric Acid, Anhydrous Ammonia, Metallic Sodium, Chlorine, Liquefied Petroleum Gas, Liquefied Hydrocarbon Gas Motor Fuel Anti-Knock Compound, Vinyl Chloride
Steel Forge-Welded or Fusion-Welded Tank with Manway Nozzle
Insulated
Top Unloading Arrangement Required
Safety Valve (225 psi)
Bottom Outlet Prohibited
Bottom Washout Prohibited

ICC 105A500 (obsolete 8/31/56), ICC 105A500-W, ICC 105A600 (obsolete 8/31/56), ICC 105A600-W: Chlorine, Carbon Dioxide, Anhydrous Hydrofluoric Acid, Liquified Petroleum Gas,
Liquified Hydrocarbon Gas
Steel Forge-Welded or Fusion-Welded Tank with Manway Nozzle
Insulated
Top Unloading Arrangement Required
Safety Valve (375 psi) (350 psi on Carbon Dioxide Cars)
Bottom Outlet Prohibited/Washout Prohibited

ICC 105A100AL-W, ICC 105A200AL-W, ICC 105A300AL-W: Fertilizer Ammoniating Solution (Ammonium Nitrate Solution) (V.P. not Exceeding 75 psi @ 105 deg. F), Nitrogen Fertilizer Solution (Ammonium Nitrate Solution)
Aluminum Fusion-Welded Tank with Manway Nozzle
Insulated
Top Unloading Arrangement Required
Safety Valve (75 psi)
Bottom Outlet Prohibited
Bottom Washout Prohibited

So, note now the many 105's you could get. The ID on these cars is in the small writing on the right side of each tank side, and it takes sharp eyes! They progressively get stronger and stronger (thicker as well) steel (or aluminum) tanks, with progressively higher pressure capability, depending on the commodity. The "dome" is not a dome, it is a valve casing for the inlet, outlet, and safety valves. This is what the Athearn "chemical" tank was supposed to be. They ranged from a tiny 4k car, IIRC, to cars of 11k capacity (but not really), and later, by the sixties, some huge monsters like the "Rail Whale" and others. This became the second most numerous class of tank cars in time.

Model options: the Atlas 11K 6-course 105A300 car for LPG and anhydrous ammonia service, which seems to be a disappointment to some, plus perhaps the Trix 6K 105 for chlorine to those water treatment plants (maybe supplemented by the upcoming BLI car?). For post-fifties models, there is the old AHM offering (a GATC 105A300-W), but with badly needed upgrades, which models a rather uncommon car used by folks like Domino Sugar, of all people. There are also several OVL brass cars that tried to render a 105. One 7-course 11k car is pretty good, but there is another ~8k 5-course car that has no real prototype, sad to say.

More to come....

When this series of very informative postings is done, could someone gather them and install them in the group data files?

Is there a publication or website that has this information across other car types?
