This does not fit Welch Allyn handheld power pack based instruments. It appears to follow the same design and is the same size as similar Welch Allyn blades, but the horizontal rail onto which the blade mounts is too thick on Welch Allyn power packs to accept the Portex blade. I suspect someone handy with a small grinder could take care of this issue by honing out the slot on the blade.
This blade has seen little, if any, use. It appears well made and to be in good condition.
