Well Jim, the markings at the top of the front panel above the CRT show the
model number. This should be the case and I've never seen or heard of
anything different on TEK scopes. -And I've been a TEK
collector/enthusiast/user for _decades_.
As for studying how to care, use and feed these wonderful pieces of
engineering, please go to this URL:
http://www.reprise.com/host/tektronix/home/default.asp
-and rumage around.
It has much of what you (or anyone, BTW) need to begin understanding TEK
scopes in general.

Check the above site. It has a basic use section. Doesn't have pictures of
the 535 or 545* scopes, but you'd know the model from the front panel ID. I
don't have a scanner at this time, otherwise I'd put up scans from my 535
and 545B manuals.
Look at this page for a bit of Heaven :-) (IMO)

Have fun learning with it Jim.
