Nice bike! These used to be everywhere back in the day. When I worked in the bike shop (I'm begining to sound like Uncle Albert from Only Fools And Horses with that phrase), we had terrible trouble with those bloody Huret gears. They were crap. I mention this to make you feel better about your modern purchase!!
It looks like you are on the biggest sprocket/chainring? Chain might be a bit on the short side (probably due to the extra length you now need to get round the new long cage mech) - but could be worse. As you say, the bend on the gear cable is a bit tight!
Bike looks in great condition, nice one.
