Flat DHBP's, which SN 178,547 ( 1917) has, started being used by Parker in 1921 and were phased in as old stock spurred plates were exhausted in the various sizes.
Whenever I have reason to doubt the originality of a buttstock, I check for the SN stamped into the wood below the trigger guard tang. Its done in a particular manner, and can be added to a non factory stock, but it is a good place to start.
