B737
Let's imagine that 50 years ago, the person in the world who knew most about the 737 had fallen asleep and then woke up today. He's taken to a hangar containing a 737-max8 and allowed to examine it all he likes. (Any text saying Boeing or 737 has been removed.)
Would he recognise it?

No, the 6 pack is the recall thingy/attention getter for annunciations outside your eye line.

Yes the 6 pack refers to 6 annunciator lights arranged together. To maintain a common type rating for all 737s the cockpits are much more similar than you would think. The main thing he would not recognize is the 6 main flight instruments because rather than being round dials they are now contained in a PFD and ND.

The early NGs had analogue backup instruments, however later the mini PFD backup was introduced and actually required as a third attitude source for the fail operational autoflight system option. It contains its own attitude system, but gets the heading from IRS 1.
I had the six pack quite often jump out when the recall check was done too snappy. Usually a short frantic search was required to get it back and then put it back into its socket.

All the overhead panel switches come from a batch on zillions commissioned before B707 was born. After that & B727 and other had them. Now all B732/3/4/5/6/7/8/9 since 70's are still fitted with them.
