Anybody ever seen this before? (Frame Bending)
On my Del Rey, which is in otherwise swell shape, there is a strange twist in the top tube. What has happened, and what could happen here? Regards.

GamblerGord 53 is probably right. I'm guessing you picked this up used without fork? If so, that's because the fork looks worse. (It looks, as best I can tell, that the the lower lug is also tweaked. The front wheel and fork tips were probably pushed back most of a foot. The bending was probably split between the fork and top and down tubes.
I've done it. Wasn't a car but the end result was the same.

Or similar front-end collision.
Not necessarily. The Del Ray has a steel frame, and as such could likely be ridden for many more decades without failing. That said, the damage has altered the geometry of the frame, effectively steepening the head angle. The fork may also have suffered damage, lessening the effective rake. Both these can change the steering characteristics, but possibly not enough to make the bike unpleasant to ride. If the OP is satisfied with how the bike performs in this condition, there's no compelling reason to rush to replace the bike.

Yes. And besides the bending there might also be a twist if the impact was off center. Check the fork too. While this damage can be aligned it's not worth it often. Andy

I trashed my Miyata for that level of damage. Didn't have to but I saw no reason to save it. (Except tI would have saved myself a bunch of money. The replacement rode so well that when it suffered the failure that brand was well known for, I had it repaired to the tune of a near half grand with paint.) I could have straightened the Miyata to ridable, perhaps shelling out $30 for a fork.

Check the downtube. You might see some buckling marks there also. I wouldn't trust the frame. Everytime you gain big speed going down a long hill --you'll wonder how stable the front end is. Will the next bump cause the headtube to separate from top tube or downtube?? If that happens you will suffer bigly.
