Well, no, it's GURPS Standard $, not RW $, which puts it at around year 2000. The lack of weight/cost information for flamethrower ammunition is certainly a flaw, but I suspect the flamethrower in Basic is based on an M2 (43 lb empty, 68 lb full), which puts a full load at 25 lb and maybe $10, though you might need to make your own.
