Complete 3 Speed.... Your thoughts !!!!

Out of a 72 Duster. Goes in all gears real good, Has the shifter and linkage with it. I also have the shifter handle for it as well. Bell is in good shape, no cracks. Clutch Fork boot is there as well. Lets just say it will need gone through since I'm not very knowledgeable on standard trannys. What would this sell for or should it go to scrap? Thanks all. Photos attached.
