Thank you for using Just Answer! My name is***** am reviewing your question and will provide an answer or a request for more information shortly.
OK - Hibbard, Spencer, Bartlett & Company were a hardware company in business in Chicago from 1880 through 1962. They sold utilitarian ("affordable") shotguns. The Cruso model was a well known, well working gun during the time it was made.
Like Sears, HSB didn't manufacture the guns, but private labeled them. Both J. Steven and Crescent Fire Arms Co. made the Cruso. They were also imported from Belgium. Crusos were made from 1902 until the 1930s or so. Your gun was probably made around 1930. Based on the gun being in working order and with between 90% and 100% of the original finish remaining, the value would be from $250 to $350.
I hope this helps.
