It is a Beseler 23CII with a colour head.
A good, robust enlarger that was a favourite in school darkrooms in North America. It will handle everything from sub-miniature to 2-1/4 x 3-1/4 (6x9).
I have a pdf manual for the enlarger, but not the dga colour head. If you need the enlarger manual, send me a pm with your email address.
The lenses shown (assuming they match the boxes ) are fairly mediocre, but they will certainly get you started.
