The model 7450 was the first LPL 4"x5" enlarger. Utilizing the rigid column of the already successful 7700 series enlargers, a new lamphouse and carriage were designed to accommodate the larger 4"x5" format.  Most notable in the lamphouse design was the modular filtration system. This allowed the user to purchase the enlarger with the filtration system that best suited their primary needs, but the other modules could be purchased as accessories, and be quickly and easily interchanged to reconfigure the enlarger for a different type of printing.  Three modules were available - a Dichroic Colour Module for colour printing, VCCE Module for printing on variable contrast B&W papers, and the B&W Diffusion module for printing with graded B&W papers. 

This innovative new enlarger was enthusiastically received in the marketplace. In the USA, the LPL model 7450 was marketed by the Saunders Group as the Saunders/LPL 4500.
