In the first picture the press on the left looks like a Pacific shotgun reloading press from the late 60s to early 70s. Probably a DL-155 like mine. Note the automatic primer feed on its left. Note also that the clear plastic powder and shot reservoirs are missing. They might be in another box of stuff that typically comes with old reloaders for sale. If not they can be replaced, I've recently seen new ones on eBay. The manual is available from the Hornady web site. My DL-155 is still making shotgun shells for me. Manual here:

This DL-155 press was made during the transition period after Hornady bought Pacific, changing the color from blue to red. Any reference to Pacific was dropped by the mid-70s. More info:
http://pacificreloaders.awardspace.com/Pacific%20DL-155.htmThe item in the right of the first picture and in the second picture is a MEC (Mayville Engineering Company) single-stage shotgun reloader of some kind. I'm not very familiar with them. The shot and powder reservoirs are not mounted, but could be in a box. Spare parts are easy to come by.
The third picture is a powder measure without its resevoir mounted on a bench stand. Don't know the make or model.
The last item pictured looks like a Hornady 00-7 single-stage press. Note the dual link arms connecting the toggle to the ram. The 0-7 press only had one. With some clean up this could give good service. It's an 'O' press which is stronger than 'C' presses so you could reload rifle as well as pistol cartridges on it. And it has the primer catch tray. The manual is available from the Hornady web site. I am using the predecessor to the 'O
x-7' press series, (the 'Super C') and it's still going strong. Manual here:

The powder measure needs a resevoir to hold powder, but appears to be adjustable and could probably be used for pistol reloading. There is some rust, so it might take some TLC to put them back in shape. If you're interested in a project, it could be worthwhile. Equipment like this can last a lifetime if you take care of it.
