Cat lamp EHZ (Eugen Hechelhammer Zehdenick) — aroma or not?

Hello! Could you tell me, please, is this aroma lamp (rauchverzehrer) or not?
There is an isolated space inside, where theoretically you can drop.
I'm also interested in what year the marks is? I couldn't find information about the year.

 

Here is an aroma lamp on Etsy https://www.etsy.com/listing/155895...how_sold_out_detail=1&ref=nla_listing_details and an oil burner on ebay https://www.ebay.com/itm/334054385561

 

Huh. Never heard of an aroma lamp before. Learned my something new today!

 

Not an aroma lamp but a night light made during the 1950s.

 

It's called rauchverzehrer. You can read about it here) https://de.m.wikipedia.org/wiki/Rauchverzehrer (Cited from: https://www.antiquers.com/threads/cat-lamp-ehz-eugen-hechelhammer-zehdenick-—-aroma-or-not.86813/)

 

Tell me please how to distinguish an ordinary lamp from an aroma lamp? There is a recess inside the lamp.

 

Like an early room freshener!

 

Are the holes for allowing heat from the lightbulb to escape?
