It depends upon when the gun was shipped from the factory. As a general rule Lend Lease guns with the V serial prefix would typically have shipped with smooth walnut stocks. The earliest, pre-Victory Lend Lease guns were shipped with checkered walnut service stocks with silver medallions. Beginning in the mid 900000 range +/- there was a shift from the checkered stocks to the less expensive but just as functional smooth walnut stocks.
