My reply from Puritan. I have further inquired about what info they have about setting up their machine and haven't heard back. This machine must really be an odd ball.
Dear Mr. Hale:
Thank you for sharing with us the photographs of your very
interesting old machine.
Your machine does not resemble any type manufactured in the
past by Puritan, nor does it resemble any other machine with
which we are familiar.
We can provide basic advice on timing and adjustment of
a needle and awl chainstitch machine, of which type is
Puritan. Some of the procedures we use for adjustment of
our machine can likely be applied to your type.
Additionally, some of our screw threads may be same as in
in your machine. The threads were one of many standards in
effect over 100 years ago when Puritan was founded, but
have become lost to time. We continue to support older
Puritan Machines.
We wish you luck with your machine.
Best Regards,
Drew Papanek
