That BB is from Slovakia. Found on mid to low end stuff - mid 90s. Tending to agree it's something from the continent.
Miyata had riveted cable guides, it's not one of those, and it is not a Cannondale. Nor a Klein. Sadly there as been so much generic AL stuff churned out it's really difficult to ID things like this. Even if you whip the forks off for an ID on the steering column, it will only point to something fairly generic from Taiwan.
By the way, your shed looks like a Tardis. Much bigger on the inside.
