Your Spencer Gun Co shotgun isa "Trade Brand Name" shotgun. That is a shotgun made by a major maker usually for a wholesaler or retailer who chose the name to go on the gun. In this case the gun was probably made by the Crescent Fire Arms Company of Norwich,CT (1892 to 1932) the largest maker ever of such guns. It was made for and sold at wholesale by the Hibbard Spencer Bartlett Co of Chicago, a large dealer in sporting goods. Best guess on a date would be sometime between 1910 and 1925.
The forearm is the front part of the stock, under the barrel, that your NON-trigger hand holds.
