Well, what can i tell ya. Sometimes we can't have everything we want, sometimes we can approach it. Will the owner of the model 60 let you make payments, put it on layaway, or work it off. Part time job might impress the owner to give you a break w/the promise to pay. Search for things you can sell here on the forum or elsewhere.
I can almost give you a guarantee that there will be another model 60, .357 magnum w/3" barrel that you will like almost as much in your future. Maybe a lesson here is to save some money, have a stand-by emergency gun fund. Until you get that fund, might be a good idea to stop looking for a new gun, might help your disposition.
But hay, give it some thought, you might just come up w/a way to get that gun. 'Tis the season you know, maybe the owner of that gun will get the Christmas spirit. In the meantime, have a Merry Christmas.
