Thank you, Onmilo.
No, there is no disagreement to settle. I just watched a 1941 movie on Turner Classic Movies entitled, "Unholy Partners." Imfdb.org did not have that movie listed so as to determine the exact Colt models used, but I guessed that at least the 1903 Pocket Hammerless was used. The 1908 Hammerless in .38acp seemed to be in it as well.
I just chose the 1908 in .380acp to be representative to me of the thin width of that series of sleek-looking pistols. When I look at all the mini pistols out there today as threads abound discussing "pocket carry" pistols, I sorely wish someone would manufacture something like it again in steel.
I appreciate your time.
