Will a standard ribbon reel fit on this? (Staples) or do I have to custom order this?

Generic spools from Staples will work, but the ribbon reverse might require grommets to work properly. I use standard ribbon in mine and it doesn't seem to be an issue; worst case scenario you would have to either put in a couple of grommets yourself, or even easier, just manually reverse the ribbon direction when it gets to the end of a spool.

 
Thanks Uwe
I'll problary get a proper ribbon I'm sure everything's working as it should be but for now a cheap generic ribbon to test things out seems to be the route I'll take. Thanks for your reply. I just needed to know it it would work.

I have completed my work on this typewriter. Thanks all. Thanks the typewriter-man. I appreciate your help immensely. I may not have been able to complete the job without you.

I still need to purchase and install a proper ribbon on this. (I had an old one I installed as I needed to know if all was working).

I have decided to give this typewriter to my daughter. She has always wanted an antique typewriter and I don't know if I'll ever find her anything older than this!  I'll try to find myself another Underwood Standard some day. I'd like a 5. Oh well. Only one daughter.
