"Sile" is often found stamped in the stock. Converting service rifles to sporters was quite the industry. There were other businesses making sporter stocks.
I mentioned Sile making Savage .22 stocks. Saw a batch of them at the Savage plant in Lakefield, Ontario. Bubblegum pink for a KMart order. Thousands of them. At the time, Savage could source them cheaper delivered from Italyicon than from the US.
