Been a while, but I recall the spring staying on the hammer when the ends are removed from the block. It doesn't go flying anywhere.

Lewis, the coil spring for the hammer is not a puny thing. Hard to lose track of. The one you should be concerned about is the lever tension spring. It often goes un noticed when the Rifle is taken apart by some one who is not aware of it's existence. It is under the lever and is inside a small plunger that bears on the lever to keep it tight, it is up in the front section of the receiver. It can easily fall out during disassembly and not noticed. The Plunger is about 1/4" in diameter and less than 3/8" long and the spring that tensions it is even smaller and shorter. These are not often found for sale and are a pain in the butt to make new, Trust me. HTH, Regards. FITZ.
