I have just 1 enlarger.. a Dust S45. I have a full set of condensers and the following lenses 50mm Apo Rodagon, 63 mm N El Nikkor, 105MM Rodagon, 135mm Rodagon. I have a regular condenser head, a point light source system and an cold light system. I have a full set of metal masks. I have a Condit oil immersion, pin registered carrier and regular and a vacuum easel. This is certainly all the enlarger I can use.
I find it hard to understand having more than 2 enlargers.
