Bag of 15 Springs ... maybe 16 but certainly 15 ... never 14.

Made of steel and they fit the revolver & any other sparrows lock - Not sure if they will fit that European Yule wizakovtiz you found on ebay that has been modified with parts from a Ford fiesta and that key you found in the Wendy's parking lot but give it a go.

Square Burgers .... did you know that Dave the founder of Wendy's was a high school drop out. At age 61 he went back and got his GED. The graduating class voted him most likely to succeed. Lol  !!
