looking at this 54,its a canadian monarch,not a mercury.the lucerne name on the quarter panels and 'double side trim' is an easy difference to tell them apart.we have a blue 54 monarch identical to this at our place.the two 54's in the background look like more parts.oh,by the way,nice jackstands!
When I was in high school in the 60's my brother bought a 54 Merc 2 door that had a glass roof. He paid $30 for it in a junkyard and we put a 292 V8 in it and he ran that thru most of college. It was rock solid and my father had it crushed in the 70's. That car was a blast and I think he had about $150 in the whole thing. Those were the days.
