Hi,
I am looking for a cheap or/and easy to find lens for 16x20in? It would be for photography on paper. Can anybody help?

Kodak Anastigmat 21 1/4" is one of the lesser expensive lenses, I've had good experiences with a 19" RD Artar, a 360 Componon and a 210 6.8 Angulon as well (for contact printing purposes, at least)
use one of your existing shutters from another lens (copal 3 or BIGGEST shutter you got) and +1 diopter close up lens/meniscus...give you 1000 mm lens which should cover pretty good...just no "corrections"..but maybe none needed....
stop it down if you still get some shutter vignetting0--and to sharpen the image nicer...it works....hey--at least something to play with and get a feel for it, you know?
Protar VII f12.5 23 1/8" focal length will cover 18X22 at smaller apertures with full correction and sharpness. These are usually sold combined with another Series VII lens to give a faster (f6.3 f7, f7.7) shorter focus lens. So if you buy a Protar VIIa that includes a 23 1/8" f12.5 element or a 27" element, you'd be good to go.

Even cheaper. 26" or 28" element from a Turner Reich 8X10 triple convertible. Not as good as the Protar, but cheap cheap cheap.
I've used a Zeiss APO-Tessar 450mm f/9 on my 16x20 with good results.
ha HAAAAA...do I know the audience here or what?
just start with a regular diopter---walgreens cheaters if thy got them big enough lenses...tape to the back of a shutter and play...
doublets in long focal lengths start to get EXPENSIVE and small...better off getting a proper lens in that case....
anything you need will need LONG focal lengths and will, of course, necessarialy be slow
like i said...biggest shutter you got--or no shutter---just longest lens you can find, which is probably a diopter....if you stop it down enough it can surprise you....if you want to start getting sharper, I suggest a proper lens--no sense in re-inventing the wheel--you'll waste time and money and end up buying a proper lens anyways--besides--if it dont work out, you can always sell it--you'll have a hard time selling a homemade piece of crap...only one person I know of can do that.....
