I a 50s-era Montgomery Wards Hawthorne girls bicycle that I broke down into parts and will have them offered for sale. I have included a picture of bike as I bought it.  Any experts out there are asked to let me know what I have. Told everything was original.  Thanks for looking.

From a great question:

Overall length is 5.5 inches, red part is 3 7/8 inches long,  overall width is 2 3/4 inches and height is 1 1/4 inches.

From a comment received:

These pedals can't be any older than the 50s so they are not original to the bike. Price adjusted accordingly.
