Hello all thank you for your kind words .
Yes aluminum Mi-Loco
Die-cast ...intended to be Mi-Loco ...but sold under Mini- Scale name by Congress Tool & Die ....who did the tool and die work ...company is still on business.
Both companies used rear wheel drive ..enclosed drive gears ...great runners .
Here is a link to see the Mini Scale Hudson pulling a string of Mini Scale passenger cars ...all die cast ..all very heavy..all glorious 17/64ths
Yes tender is lettered Mi-Loco ...this is very early factory built example ...before Congress Tool and Die ..took over sales .
Also note observation ...Mini- Scale only made a combo and Pullman ...obs is from a modified Pullman ...Hudson is maxed out pulling the 4 Mini Scale cars .. and express Refer
