... and I just filed down a 4mm allen key to fit. But as you correctly noticed, Tom, both items are from the same era (off-topic, dare I say) and before that everything is aok. And what about the 7mm french stem allen bolt. I think the french are the worst at mix´n´match. you will find bolts sizes ranging from 8, 9, 10, 11, 12 (if you´ve got a bolted stem), 13, 14 (if you´ve got one of those stupid saddle clamps) to 15; and a mix of allen key bolts on top of that. If you´re really lucky you´ve got 6mm drop-out adjusters as well!
