The Lobaugh cab forward and Daylight GS appear in the 1942 Lobaugh supplement, just in time for Pearl Harbor. They were not brought back after the war, so, yes, rare.
The Lobaugh FEF, B&O pacific, and D&H challenger appear in the 1941 catalog and likewise disappeared permanently with the war, so also rare.
The MP mountain and NP challenger were introduced in the 1940 catalog, so they wouldn't be so rare if they sold as well as the 0-6-0 or C&NW Berkshire, but I guess they did not, as they are not seen often. I have never seen the MP mountain.
I believe the suburban tank locomotive, like the one on eBay, is a post-war model, but I haven't scoured the catalogs to find it. I have only seen one, which my eagle-eyed brother spotted at the March Meet in 2016. Arthur Hayes was alerted and he scooped it up.
Other post-war models that are rare in my experience are the climax (seen one) and the mongrel mogul (can't recall seeing any):
