Need help with parts and schematics for a Crosman 400 .22 caliber Repeater air rifle.?

if you go on the crosman sights follow a few links you will eventually find on the internet a manual of every piece and all the info of the gun, you could then send it to a crosman specialist guy and they fix it for cheap. i live in florida and i use a guy in north carolina for even a crosman 600 which is a mid 60's air pistol repeater
