Oscillator not working at indicated frequency

>They got me about a year ago in a very similar way:
On every xtal I have [about 20 different frequencies], the labelling
matches the freq in an "obvious" way.
And don't let Bob steer you wrong on D-K [probably not his intent].
I order from them all the time, and have had few problems.
However, last week I did get a salesperson [man] who was apparently
very new, and screwed my order up in 3-4 places. In your case, simple
difference between entering P/N SE3438 and SE3436. Just imagine
having a job where you have to enter 20,000 of those friggin P/Ns
every day --> decreasing IQ and brain fog and "terminal" stupidity.
BTW, I have used 3 or 4 different 20mhz parallel-cut xtals from
D-K - although not the cylindrical-type - with several different
PICs, and never had a problem.
