"Ishwata" is a Japanese tubeset I think. Doubtful that would be used on
a European frameset in the 1970's. Now that I think about it, Columbus
tubing which was used by the European manufacturers is a chromoly set .
.. . but without a label stating its use, it's probably not an alloy
frameset.

In the era we're discussing, there wasn't much "contract" building by a
manufacturer for another label. I'm not saying it couldn't have
happened, but unlike today where there are relatively few actual makers,
but there are tons of marketed labels, in the 1970's, there were really
tons of makers.

Yes. The ambrosio was a cheap Italian rim.
When did ****mano first develop the QR axle system?
Don't exactly know but remember "San****n" QR hubs (another Japanese
component manufacturer) as early 1973 and presume that ****mano developed
around the same time.
