The Talking Machine Forum — For All Antique Phonographs & Recordings

Need a main drive gear, the old one is worn to the point it slipped and ground all the teeth off. Pictures attached.

I believe it's the standard bull gear of the post-1921 Burton (?) motors for Victrolas, same as hmv 32 &34 this side of the pond. Any of those will match. You'll find them this lighter fashion with the four big windows, or as a complete steel wheel (as in my hmv no34 motor). Still all them are interchangeable.
George Vollema or any other parts supplier can sell you one just for peanuts... Or you can look at eBay, although a professional parts seller would send you one in good shape and tested for proper and smooth running.
