What are the Needle/Thread size options i would have as it is now? Also, motor recommendation for this machine? And thank you Constabulary and Uwe for the information, I really appreciate it.

Across the back side, when looking closely, there is the remnants of "Wheeler & Wilson".

I want to find out what make and model this is, where I can get a manual or parts list, what it should be capable of sewing. Everything moves freely and smoothly. Any info would be greatly appreciated.
