These privately printed stocks and bonds are of superior quality. At the other end of the spectrum, some printers or lithographers use lesser grades of paper. They make books of bonds or stocks for non-contracted companies, with company name to be printed after purchase. This lower grade paper may require closer scrutiny while repairs are being effected. Repairing stocks or bonds is not looked at with the same disdain as doctoring a coin or washing and pressing a banknote.
Most glues used for attaching stubs are water soluble, as it's the least expensive.
Stubs can be removed by soaking only that portion of the stock in warm water. After a few minutes, remove. Scrub glue off, wipe off excess water from both sides and place in thick book between two pieces of clean, white paper. If you wish, you can add a few books on top of the pressing book to assist in complete flattening of the stock. A drop on a cue tip is sufficient.
