Reed 204 1/2 R Restoration

[7LitreGalaxie]

Hello. This is my first post on the forum.

I'm in the process of restoring a Reed 204 1/2 R vise. I need a few parts to complete the project.
1. main spindle and handle
2. base swivel bolt(slotted head)

Is there any interchangeability with other Reed models like the 204 for example or others?

Thanks!
