How to know the model name of one device name and vice versa? Let's say we have Nexus 7 2013 tablet which has model name to be NEXUS7-2B32.

I have difficulties in choosing the device items on ebay - the right model to buy only came from model name, not from the title/text name given by the sellers.

So my question is, where would we Anroid users can see the list of model name and its marketing/device name accoringly?
PDF at this link may help you List of all devices supported by Google Play

There is also .csv available 

Devices are listed in the following format - Marketing Name (Build.os.DEVICE/Build.os.MODEL)

Against your query of Nexus 7 2013, it returns two occurrences

Retail Name : Asus

Marketing Name: Nexus 7 (2013)

Device : deb 

Model : Nexus 7

and

Retail Name : Asus

Marketing Name: Nexus 7 (2013)

Device : flo

Model : Nexus 7
