Kodak Pan Masking Film 4570 (Estar thick base) is a standard item shown in
the Kodak Professional Catalog (Kodak Publication L-9). It is available in
4x5, 5x7, 8x10, 10x12, and 11x14 sizes. The Kodak stock number for the 4x5
is 153-4304, and this size is available in 50 sheet packages with a list
price of $73.20, but (as you know) sensitized materials prices can fluctuate
wildly. If you can call Kodak on their 1-800-242-2424, Ext 19, you can get
full details on availability in your area. (I don't know if the 800 number
extends to Mexico! If not, contact the Kodak distributor with the above
information.) Incidently, there is a Kodak manual on this material; it is
Kodak Publication Q-7A, available free in quantities of one.
