Hello, I recently picked up this Remington Standard No. 5. Mechanically everything works, but has some cosmetic work to be done. I've been googling similar machines but noticed a few odd things I am hoping someone can point me in the right direction on. 1) The ribbon spool has two wood dowels on either side which appear to convert it from a 1.5" ribbon to a standard 0.5" ribbon. Any ideas? Never seen this before. And 2) the front where it says "Remington Standard No. 6".... it appears that the "No. 6" was re-lettered as I can see the white outline of what appears to be an older letter. Was this common? Or is this not actually a '6'. Thank you. Jim.

I should also add, if you have any good information on this machine, please share.
