Will this motor work? Is the extended top part the difference in the motors? Is that a decent price?(for those of you work on electrics)

I watched her swap out another motor so I am thinking of repairing this 503a. It needs the different motor, the bobbin winder, and the top lid (which has all the instructions for the cams). I have a full set of cams and my daughter was playing with it yesterday and man did it have a beautiful stitch! The tension needs adjusted but it was still awesome. I'm thinking of repairing it and gifting it to her if she wants it....and if not then I'll sell it and say I got the experience of working on one...lol. She seemed interested at the moment, but she's 23 and sews rather sporadically :). She actually has a D9P started right now that she is doing totally on her own.
My 500a just arrived at Billy's and I'm so excited about getting it repaired!
The motor looks right but it is hard to say from that picture. I wonder if the motor the lady put in your machine was from a Touch 'N Sew. They fit but they are not the same gear top. Can you find the lady again and swap back? Take the messed up motor in to a shop and they can clean it up. You do need one with the gear thing sticking up so the bobbin will wind - I believe I would ask the place you are looking at buying from what it was out of. Too bad you didn't change the 500 and the 503 motors out before you sent the 500 to Billy - maybe he could have swapped it out for something that would do the job. The 20 something kids love those Rocketeer machines. I gave one to my DIL and she loves it - what's not to?
