Just noticed your avatar having a Nationalist badge on it (?) I read a story regarding Nationalist and pistols from the memoir of a former nationalist agent, whose role was like "Agent Smith" in the movie "Matrix"
In 1949, his agency hided some Thompson, Mauser, and Browning into a few coffins for future undermining work in Shanghai. In the hiding site, one fake tombstone marked "Beloved Daughter Mau-Ning's Tomb". Another tombstone marked "Uncle Tang's Tomb". In 1950s, he was captured and confessed everything. Thompson submachine guns were digged out, but Shanghai public security could not find the coffin of "Mau-Ning" anymore. It's lost.
