To me it looks like some kind of European trekking bike. Often trekking bikes have the forward facing brake bosses on the seatstays to allow those built in u-locks the Germans and Dutch favour. Maybe the bb threads are not original and one of those press fit bb's like a Thompson was fitted then locked in with the clamps. The lower top tube to allow easier dismount when fitted with loads of luggage. Dutch cycle tourists do seem to carry everything and the kitchen sink compared to lighter British loading. Interesting steed anyway.
