american flyer standard gauge train set cast iron engine-metal cars 4672 type IV

nice original paint on everything although some is missing from use and have yorktown names on each one total of 3 cars,the tender has number 4671 stamped underneath,the engine is cast iron and heavy,it has new wheels and possibly linkage,it does run and lights work,this is an old set from late 20's so it does not look new.Hope this is a fair price for all,thanks.It is a 4672 type IV engine and tender with the most elaborate linkage for this type of engine and firebox light.The cars are 4141 type I and 4142 observation type I
