Searching an IBM Model B typewriter for IBM 1620

[Johannes Thelen]

I got just another jewel to my collection, IBM 1620 Model I (G level). Machine has all internals intact, but table top and the typewriter are missing (probably doorway was too narrow back then, parts removed and forgotten somewhere on the journey... )
That table top can be made again, but I would need that right model typewriter. Anyone have a spare..?
Also I have another problem with it, memory is suffering wire corrosion (like these all does). So this can be a looooong shot, but if someone have a functional memory or just core array, I'm interested to buy or swap it to something.
Photos can be found my blog, link below.
Thaaaaanks!
