Not Judi.
I'm going to keep it locked for you till your next reply.
I've an article about this car and many pics. In one of those there is this woman with Mr Mackerle and I can presume she was his wife ('usmėvā' can't be translated with google
).
take your time for your guess, I'd prefer to award the point to the person who find the car rather to who will get 2 letters right!
