I've been to a lot of hardware stores and discovered that you can no longer buy staples for the old T5 stapler. They now call them T50 and the staples do not fit my old T5, i have a T50 already but my old favorite is now a useless bit of tin and springs. I even looked on Amazon and Bostich's site and they all just go to the T50. Guess i will have to watch auctions and such for ammo for the old T5.
