Er, well, to be honest, there's nothing that you really can do without a parts machine... You could 3D print one, but that won't be doable everywhere until 2030 and by then you'll find 3 parts machines. And I haven't tried it with my brother's printer yet, so who even knows if it is possible. The best thing is that you hope you'll find a parts machine soon.

Make sure you put up a "wanted" list in your signature with the items you are looking for. I come across odd stuff all the time, and who know... maybe I'll find a trashed Smith Premier No.4 one day and be able to supply you with those missing typefaces!
