It's going to take awhile the motor sides were taken apart drilled and tapped and hot glued together.I don't know if I should just buy a new motor(one on ebay for 75.00)or dig into this one.

I have found tremendous satisfaction in repairing things as opposed to dropping in replacements.  Good luck!

dig into the motor you have since...you already have it. 

As for the identity of the motor, yes, on the Type 4 motor, which is the only one to use that style of brush plate.  The body itself has all the characteristics of the 152 loco.  The way the handrails are attached, "Y" shaped stanchions, with wire handrails, is one of the giveaways.  In all of the 150 series locos, NONE had two strap headlights.  They were 1 strap headlight, with a Bell on the opposite end. These were manufactured from 1917-1927, whereas the first issue (1917) had a Type 2 motor, which was later changed to the Type 4 motor.  It appears from your photos, that the motor is missing the collector plate, but if you have it, it should say "Lionel Corporation", dating to 1918 and later.  

Your motor looks salvageable, but you would have inventory what parts you need, weigh the price for all the parts, versus finding a replacement motor.  If you can find a donor motor, for less than the cost of the parts, then I would go that way.

I checked on the eBay listing for your motor, and calculate the price, with shipping, and needed parts would bring the price to about $150 ballpark figure, if that is one of your choices.

If you decide to tackle the existing motor, the needed parts are well under $100, and more in the $60-$75 range.  The motor you have, can be restored, with some new parts, and some patience  T.L.C. !!  Your decision.
