Want to machine my own Marauder breech

Where might I get a dimensioned drawing?
Thanks for the help.

The only place I  think you will find one is if you find someone who has taken the time to measure and draw one. You will also be missing the factory tolerances as the only place that will have those is Crosman and I doubt they will want to share.

I did a rough solid model of my .22, I think I changed it to the .25 version once I had one of those. I'm not sure on it's accuracy and I remember that it is not finished (mainly the dovetail scope mount). The .177/.22 breach is different in a couple of ways from the .25.
