Yes, it's a Huffy make. Sold as the Huffy Daisy Daisy and by several other sellers with other names. Huffy and most other bike manufacturers would make bikes for many other retailers. Yours appears to be one sold by Sears. The 505 (sears supplier code) is followed by the catalog number 459910 and then the serial number is the second line. There are many hundreds of Sears suppliers with many code lists on the www. Wishbook has many of the catalogs scanned. Each year is text searchable so you might find the actual catalog page (tedious search).
I owned two of them. Photo later.
The Schwinn head badge is bogus.
The fork is a Schwinn flat blade model off a single bike. Possibly from a Varsity or a Collegiate or one of the 3 speed models, Racer, Breeze, etc.
The original cranks are lousy. The right side bearing cone doesn't thread on. it's a slip fit (loose). The chain ring wobbles and is held in place by over tightening the bearings. The chain jumps off often. I replaced the cranks in mine with Schwinn cranks (threaded right side cone) and it worked much better. Any crank with a threaded right cone would be an improvement.
the rear end is prone to collapse like many other girls frames. Mine was reinforced by shoving a second seat post way in. A double wall seat tube if you will.
I had two of them in the late 1970s. One came with a Schwinn Twin tandem fork (far stronger than the stock fork). The other fork was bent. I welded my two together to make an in line 4 person tandem (quad). I used the Schwinn Twin fork and it's held up despite the extra load and much abuse. Here are photos of us riding it during Ragbrai in 1982. Kinda low rez as the photos were from a different century.
