Try eBay. That's probably the best source for miscellaneous items. B&H and other mail order places also sell enlarger lenses, and you will get a better guarantee and return policy if something is wrong. There is someone who sells manuals on a CD, but I don't know if it includes Vivitar. If not, find someone who is selling a model like yours and inquire whether they have a manual they are willing to share with you. I have found manuals for various darkroom equipment items this way. Just return the favor to others some day.(posted 8278 days ago)
