Extraordinary Marklin SLR 741 passenger set with 3x 340 series cars, SLR 700 locomotive in very good condition, and a rare 3600 AR regulator track which was only offered in sets for two years. This set dates from 1936 and was only offered like this for one year! The later 1937 set has a red box and was redesigned. This set comes from the East Coast and even came with a few historical photos probably from the original owner! Amazing and rare complete set from the pre-war years.
