Ole Sommer was, as you've said, a major Danish Volvo dealer. Around the same time Jacques Coune was creating several drophead Amazons (not to be confused with the Volvoville and Radford P1800s that came later) he decided to create a one off coupe. The body was hand fabricated off a wooden styling buck and the rear screen came from a Jaguar XK150 (presumably one that hadn't been banger raced).
There's more in Walter Wolf's book on the Amazon if you're interested. I don't think my Anders Clausager history of the 120 series mentions it.
Interesting. Never seen that before. The shortened wheelbase has made that rear overhang look reeeeeaaaaaaaallllllly long. Relationship of front screen to side windows looks a bit odd to me too. Maybe the screen is actually another car's rear screen?
Follow your dreams or you might as well be a vegetable.
From AD Clausager (The Essential Volvo 120 Series And P1800):
'In 1960 Danish Volvo dealer Ole Sommer had a one-off coupe built on a shortened chassis from a PV445 estate car, incorporating 120 series panels for the front end while the rear body was hand-built with aluminium panels. The car used a twin - carb B16 engine. Its windscreen was a 120 series rear screen. The seats, rear screen and other parts were taken from various Jaguars, a make for which Sommer was the Danish agent. The car was originally sold, but in 1968 it was bought back by Sommer and added to his sizeable private car museum on the outskirts of Copenhagen.' (1996: 35)
