It looks like a red eye treadle that has been converted to electric but has all the treadle mechanism with it. Check, if you can, whether the presser feet clamp on the side or the back..if it is a side clamping machine you will have no trouble using modern presser feet on it (except a walking foot and even that can be adapted I'm told). The rear clamping machines need special feet. It should take standard metal class 66 bobbins and is easy to clean and oil. I have a 1913 red eye treadle and love it.
