Solved: PN #984 -- Opel Blitz by Radochla

Helping out here: it is the Karosserie-Fabrik Friedrich Radochla.

Thank you! I must've stared at that thing for close to an hour, seeing RadBehla, RadBehld and a bunch of other stuff that made no sense at all (RadBchla, RadBchld, Radßehla, Radßehld, Radßchla, Radßchld, and so on). My brain never registered the fourth letter as an 'O'.

I hope you don't mind but I gave both gte4289 and Wendax 1-1 points each

Congratulations

Thank you for this unexpected (and not completely deserved) point.

Thanks to you both.
