I'm looking to upgrade the BB and cranks on my bike and i was wondering what are my options for it?
Here's the bike. From what i've read there's different versions of this bike (european, french, english)? and it's all a big mess in my head now. There is a number on the bottom of the frame but i can't remember it off the top of my head.

I was wondering whether or not i could get a Shimano 105 BB and a Sugino Messenger crank combination? or are there some sizing/dimension issues?
If not, what other options have i got?
Any help would be massively appreciated.
Thank you kindly!
