Not really enough info to comment on. Size of the frames can mean much as to why things are.
Also, do not believe published angles. You have to measure yourself and accurately to really know. Including making sure your datum is level.
That all expressed, there is an evolution in design over time that can be observed.
Head tube angle is btw, a guide until you include the fork rake. Trail can be derived from that. Don't forget bottom bracket drop too, all of this can and do influence a bikes handling and performance.
