Marx No. 5424 Freight Terminal Playset from 1952! 

Very cool! This is one of the less common sets, which makes it even cooler. Thank you!

That is a big set, nice. Thank you for showing us.

Very interesting Great information. 👍

Those little yellow barrels look identical to the ones Marx included in their barrel loader accessory. My dad had one.

Really COOL !!! I was thinking that this set would make a really cool add-on to the Marx Untouchables playset!

Thank you so much for posting this.
