Pepita rear triangle
I got a 1959 Crescent Pepita frameset for free and the rear triangle is bent an inch to the right on both dropouts when I used the frame checker. Can the bike be bent back?
The frameset looks exactly like this one.

Yes, where are you located? This would be an easy job for an experienced frame builder. Once you give your rough location, I'm sure others will chime in with who would be close to you for the repair. Steel frames like that are pretty forgiving.

The first rule of mechanical work is "Don't fix what ain't broke".
So before doing any "straightening", take the bike on a test ride and see if it handles right and can steer "no hands" without compensating.
If not, then you can cold set (bend) it back into alignment.

Repairable isn't the issue. It certainly is.
However, the real question is whether it's worth spending much on.
It's a fairly low end frame as evidenced by the BB construction, and welded on kickstand mounting plate.
Also, the frame has an uncommon bottom bracket and crankset, so check the condition and availability of replacement parts, should your need them.

Also when asking a question that requires the frame post pictures of the frame first. Not of some other bike, that bike doesn't matter even if it is the same model if nobody sees the problem the picture is just to show what a bike looks like and this being a bike forum, most of us have figured that out. There might be a couple call girls from Dubai who don't but hey they didn't respond to me anyway so forget them.
as FBinNY said I wouldn't put much time or effort into that bike. If you are just going to build it to put in the jackass thread or pedal room with goofy stuff than just leave it alone and waste the time building it to show something in the goofy mediocrity otherwise let it go back to where it came from and just take the wasted gas and time as a loss and move on. Loads of more reasonable frames to work with that are of better quality and components that probably aren't damaged in the frame.

Does it have the same parts as the one in the picture too? If so, it'a great old bike, well worth preserving as is. Those old Crescents have a big following and are fun to Ride, i hear! If not, it will make a cool single speeder... as stated by the others, it should be straightenable... Another factor is... Any Rust showing? how bad is it?

It's as old as I am as well. It does have a lot of rust showing, and in the worst place too. Right where the chainstays fit into the BB. A BB which it has already been mentioned will not accept modern bearings. What must the condition of the bearings be?? Rust we can't see??? An inch (25.4mm) of bend in both dropouts? It was in a wreck? I don't know. I really don't know. Well, actually I do. I wouldn't, that's for certain. It's not like this is some amazing example of the framebuilders art. A LOT of work is going to be needed to make a working bicycle out of this. Even as a fixie. I've given away complete bikes, much newer, in better shape and ready to ride.

I have straightened a number of frames with great success. The latest one the head tube had a twist that I was able to move the head tube enough to get the bike to track straight. If you are in my area I will happily help you out free of charge.
