Default Clockwork winding keys

OK, not sure about the section for this post, but as it relates to a telegraph inker I guess it's kind of vintage telecomms, but this question may be better answered by clock experts...

The clockwork motor needs a key. Do I stand any chance of being able to find one or must I start filing metal...

The shaft is square and tapered from about 5.8 to 6.2mm over 19mm length.
NB: May be a foreign make (but hard to say).

Nothing mentions being for a tapered shaft- but mine is distinctly so.
