In case you may not seen this, I've answered your inquiry in regard to the Gerber MP600 Fisherman multi tool in the Gerber thread. This may have been made in 1999, was stamped USA and is quite rare. If you upload some images here, this could certainly help as factory sealed products tend to go for more money in many instances.
Thanks for info. Will sort some photos out later in the week.
