WTB: Converted Obscure Keyboards

[User101]

Really want to try out some niche switches and strange keyboards. Vintage teletypes especially.
Something like the Teletype 40K is literally perfect.(also wtb)

Only requirements:
1. Must have spherical keycaps
2. Key feel must be decent enough for daily, don't want extreme scratchiness or 300gf weight

Will pay appropriate.
Thanks everyone.
