The Model 55 is one of Stevens "Ideal Ladies Models". It is chambered for the smaller rimfire cartridges between 22 Short and 32 Long rimfire. It has a 24" or 26" part octagonal barrel with a vernier tang sight. The finish is blued and case colored with a checkered walnut pistol grip stock with a Swiss style buttplate. Values from the 2011 Standard Catalog of Firearms are:
excellent-$6500, very good-$5000, good-$3500, fair-$2000, poor-$1000.
I hope this helps you,
I can only go by what the books tell me. It is supposed to have a normal trigger. Believe it or not, the Model 55 is the lowest price rifle of all of the models in the 50's. Following is a picture of the Model 54 which is almost identical to the 55.
I found some listings for a Model 050, 053 and 054. There was not an 055, but that doesn't mean there isn't one. I also did an online search and it came up with a Model 55 bolt action single shot with a standard rifle stock. The pictures are like any other rifle you would see, not fancy at all. If you have the Model 23 "Sure Shot", the values are still pretty good. It has a 20" round barrel that pivots to the right to load it.I guess you have the Standard Catalog, in case it is not up to date, the values are:
excellent-$2600, very good-$2200, good-$1400, fair-$1000, poor-$600
The 23 is not listed in the Blue Book either.
The following links will take you to it. You are going to be disappointed after the other guns values.
Sorry, the values are out of my control, It would be nice to have one of the other model 55's. Merry Christmas,
