Since I don't have access to an Alfa 1911 reprint catalog...a little more info would help in making an ID. The folding trigger nor the chambering of the .32 Short Colt is enough to ID the gun..both were common in the early 1900's The folding trgger is more common on revolvers but is not unknown on auto's.One common name found is the VELO-DOG series basically a handgun used to protect the riders of a velocipede from the jaws of dogs. Chamberings were from a version of the .22 rimfire and other sub caliber Parlor cartridges..like the Floberts up to 32...38...44 and 45 Check for the name Henrion,Dassy & Heuschen(HDH) of Leige belgium wsa a maker of folding trigger revolvers. One that was cahmber in .32 was named "PUPPY" offered in .22-5.5mm-6.35mm- and 7.65 mm(32) and was made as a Hammerless, a small hammer or a lar5ge hammer gun. Another nasme that made such guns was Garate Brithers(Spain) a private website that may be of some help is
