DT&I Switcher with horn?

Lionel did use that lamp assembly on some of their switchers in the 1960's. Some of the very early MPC switchers used it too.

You may have a postwar dummy truck too.

The e-unit looks to be postwar also.

In every way, it looks like a PW frame to me.

Thanks so much! So what I have is a "pimped-up" MPC switcher (lol)!! I'm not surprise now that you've shed light on this .....it runs really well, even before I have cleaned it and lubed it!!

I can think of a few locomotives that had sheet metal fuel tanks, as pictured above: the 633, 634, 635, and 645. All those engines had tire traction motors, not magnetraction. At least some of them used that lamp socket / bracket assembly for #19 bulbs.
MPC continued to use the same frame, including the lamp socket, but switched to a different bulb after just a little while. I think the MPC frames are usually embossed with an MPC part number.

Update: I guess the 617 had those metal tanks, 3 position e-unit, a horn and 2 axle magnetraction. So maybe it is a 617 chassis.

Simply a Late postwar chassis with a DT&I bodyshell

Thank you ALL for your feedback... I am almost convinced that it is a PW frame, however all of the pictures in greenberg's guide display the NW-2 switchers with a metal frame that completely surrounds the coupler.  Notice in my attached photos this model does not have metal underneath the coupler which I is what I have seen in the pics of other DT&I's for sale on eBay....

any thoughts?

Look at the link I provided for the 617.

Here it is again: link to 617

Oh, I see.  Thanks so much for your input.  I guess I should save this for when I discover a 617 shell?

There is a 617 shell on EBay right now. I am following to see how high it goes. I do not plan to bid. Nice shells can be very costly.
