Good find! Bear in mind that if you have feeding problems that a 180 barrel is a direct fit. In fact the 400 is just a dual CO2 repeating 180 so all parts will interchange should you stumble across a 180 'parts gun' on the cheap. FWIW----I've never owned a 180 that wasn't a stone tackdriver! Tom
Very Nice Mike, here's the link to the old Crosman parts diagram if you haven't already been there! http://www.crosman.com/pdf/manuals/crosman/400/C400-EVP.pdf
Nice find! Sure has some beautiful wood. Don't see too many like that off the shelf.pv
