           C-22. MILITARY SPECIFICATION MIL-L-52043, 15 JULY I    972, LACQUER, SEMIGLOSS,
           CELLULOSE NITRATE.

               a. This is a cellulose nitrate semigloss.lacquer that can be applied at
           either elevated or room temperatures. It is intended for use on chemically
           treated and/or primed tanks, trucks, automotive components and fire control
           systems. There are two types of lacquers: Composition G for general use and
           Composition L for use when required by air pollution regulations. The
           volatile portion of the material is limited by that presented in table C-43.
