Is it me, or others?

I just purchased a Kenwood L-01T FM tuner from overseas and had a strange email exchange with a FedEx US Customs employee:

KT:

The Kenwood L-01T is a vintage FM radio tuner made in Japan and will be used as a Fm tuner.   It’s likely ~50 years old.
…in other words, it’s a vintage FM radio.

KT:
What is the material composition of the radio tuner?

ME:
Ummm, what’s inside a radio?  Electrical components such as resisters, capacitors, transformers… the case is made of metal.

I’m confused by your question.  Radios are common.  Similar to stereo receivers and Bluray players.  Please clarify.

KT:
You said this was an Fm tuner.  What is the FM tuner made of?

ME:
Any AM or FM radio is a tuner (you turn a knob or press a button) to “tune”  in a radio station.  Radios has been around for 100 years and are commonly in homes and cars.  Are you asking what’s in a radio?  This seems like a dumb question, it’s simply a radio.  What’s in a common radio, is that your question?  

KT:
So this is an entire radio not a part?

ME:
YES!!! An entire working radio, nothing more or less.  Simply a radio.  This vintage radio has better engineering and sonics than modern radios that’s why I’m purchasing because I’m an high-end audiophile.
 

Am I outdated or is this person a bit dense?
