I don't know why anyone would want to see a 5x7 enlarger made today when it's utterly unrealistic to cost-effectively replicate the quality of vintage ones, which, even refurbished, are more likely to outlast anything new made with lesser materials. Last I heard, there were still a handful of classic unused Durst 138's still in crates in Italy; but these would likely fetch around $15,000 apiece for the chassis alone, plus substantial shipping cost. Hard to justify that kind of cost when so many good enlargers are going to landfills or scrap metal yards for lack of anyone wanting to haul them off for free.
