I got this bag of cloths from someone and then I saw a pill on the floor. Just trying to figure out where it may have came from. It is small round orange and all it has on it is C 135 no lines and the inscription is on both sides.

Try one of these sites:

Pill Identification Guidelines | Pharmer.org -- Pill Identification Resources

Pill Identification Resources | Pharmer.org -- Pill Identification Resources

Maybe these will help...
