1656 with a bell ringer tender. Has the operating front couplwer. I think all the 0-4-0’s had operating front couplers. I think this one was before Magnetraction.
Then you have the pre-war 1688 which is a 2-4-2
And your basic 1120 Scout
I dont think any of the basic engines had whistle tenders. All were diecast. And i think Magnetraction were for the larger engines.
Just discovered that Lionel had a bunch of 2-4-2’s in the 60’s that came with whistle tenders. #238, 239, 241, 243 and others. Seems like I forget that postwar goes up to 1969. I think of the 50’s as the classic post-war stuff. Whatever you choose, good luck
