Help! First cabinet incubator

[325jtate]

Looks to me like very well-made home-made.  I say that primarily because of your first picture.  The holes on the rear of the box, one near the top and one near the bottom, look like pre-fab kitchen cabinets. The holes are where the hidden hinge sits and attached to the door.  But they look really nicely done to me!  I'm not knocking anything, just giving an opinion.  If they work, hold temp and humidity, I say use them!  And best of luck!!

The holes on the top and bottom at the back are on both sides. They are vent holes that have plexiglass that slide to cover or uncover them.

I believe they are Phoenix incubators. What I can remember they were GQF clones with hinged backs that opened like the door. Some models had humidity controllers and an external humidity generator. Made for ostrich.
