I'll add the lettering on the slightly obscure Italian Primax seat pillar (on my 93 Longstaff trike). Pillar's OK, but trying to decipher the logo wasn't easy, the slightly wonky attempt to incorporate a bicycle (or part of) in the logotype made it worse, and the slightly irregular stamping of the letters made it still worse. I wasn't familiar with it and tried looking up all possible combinations before success with 'primax': dirimax, opnmax, oprimax, oirimax, etc.

Look and see if you could figure it out...

Here's a picture of said post itself:
