I've never seen an enlarger in person. This is a "Beseler Photo Enlarger Model 45MX" but I'm not 100% sure what I'm looking at. Is this an older looking model? It looks like a light on the base board. So is that an extra light? Is this a complete setup that would enable me to make enlargements? This is all the information I have. I'd like to educate myself a little bit before I call the seller. In general I'm looking for an enlarger that will do up to 4x5 in B&W. Thanks for any information.
