Try KHB Photographix' website and their LPL Enlarger Guide: http://www.khbphotografix.com/LPL/index.htm
KHB is in Canada, and the main model designations here are the same as the worldwide (non-USA) designations, but the listings themselves show the USA equivalents. Essentially, the lower grade enlargers are the 6700 series, and the higher grade enlargers are the 7700 series (670 series in the USA).
KHB is a great resource for information on enlargers.
But then, so is APUG .
Wish your daughter well from us.
