michael...i've noticed that you are very knowledgeable regarding schrade, so i am providing you this info....i asked the question about the silver anniversary because i have a mint 340T SS with sterling silver bolsters and shield. i purchased it on ebay in the mid 90's from an individual who told me that he was a former schrade employee and these particular knives were given to employees at a special event (maybe christmas, i can't recall). the knife is serialized 4845 and is housed in a nice wooden box. the wooden box is housed in a separate cardboard box with the 4845 number stamped on the outside of the cardboard box along with the number 34SA....in the cardboard box is a cloth bag with the words OLD TIMER Silver Anniversary. here's the quandry....the tang is schrade walden ny usa...the master blade is etched with OLD TIMER 25th Anniversary....if the blade said 50th Anniversary it would make sense...if the company was incorporated in 1904, the 25th would be 1929, and we know that the tang schrade walden ny usa started in 1948....what do you think....regards, jim
