I read that in 1913 Edison standardized motors. Can anyone tell me if that means that the motor and turntable on Edison Disc Phonographs produced after that are interchangeable. I.E. Can I use the motor and turntable from an H-19 to replace the motor and turntable in an Edison C-250?

Edison standardized motors in 1915.
This means that technically, yes, you could use an H-19 motor and turntable in a C-250. However, the C-250 was originally equipped with double mainsprings while the H-19 has only one. Additionally, the C-250 may (depending upon its serial number) have originally had gold pinstriping around the perimeter of its motor plate, but the H-19 did not. The exposed metal parts of the C-250 are always gold plated, but the H-19 parts may be either gold or nickel.
Finally, the horn of the C-250 was larger than that of an H-19, but the original C-250 horn could be retained.
Switching these parts will require some adjustment, and the result would be a C-250 lacking historical accuracy and having lesser specifications. If the original motor of the C-250 is not restorable, it would be a relatively easy matter to locate the proper 2-mainspring motor inexpensively and make an appropriate substitution.
