Last year hey ? Next year I bet my last pants yo'll tell me last millennium ! And you even quoted without Cajun technical nomenclatures ! Impressive . Yes the MIL-STD-202 does look promising . With the barometric pressures (exclusions) variations kept in mind it sounds right . Anybody tested contacts life to this procedure folks ? And, huh.,'m , please don't mention the finesse of round forms of beach pearls here ; when you go for a dip you don't know where to put yo'r eyes ; just the mention makes the work stay that much harder ; some of the fine black one's are out of this world ! We do talk pearls here, make no mistake . If only could I have a string of them .........; let's be humble ; few's enough ...... Jap pearls ? Yo've been on South East too long buddy ; must have gotten into yo' ! Way too civilised up there , no flavour ( Empress Maria Theresa [ Habsburgs - Austria ] sipped them dissolved in vinegar ) . Hope I didn't confuse you ; thanks Steve ; See yo' paul > ---------- > From: Stephen R.
