Extremely well made bulbous copper body flask with brass collar and acorn shaped tip on the plunger spout. Both the tip and collar have machined grooves. Edge of the top is knurled to aid in unscrewing for filling. The plunger body inside the flask is numbered "42". One side of the body of the flask has an applied oval brass plaque that is 2-1/2" x 2-3/8" that has the raised repoussed vignette of 2 bird dogs on point in a very detailed field scene with a hunter in the background, surmounted by "PATENT ARMS MANUFACTURING COMPANY" in an arc around the top edge over "PATENT / NEW YORK". This plaque has a raised rib around the outer edge. Edges of the flask are mounted with 4 small round carrying rings. This flask, unlike other know Paterson flasks, is not marked "PATENT" on the collar. An identical flask is pictured on pg 50 of The Book of Colt Firearms, Wilson with the caption that the embossed brass plate was attached to identify the pieces for Paterson Colt Arms. The caption also quotes: "Pliny Lawson of the Patent Arms factory is known to have advised Colt that: the flask with carbines has our hunting design on it - you must call it a seen (sic) in Florida one man with a rotary & two black hounds ...". The caption further states that although the flask was intended for the carbine, it is known that it was sold with correct spout for the #2 Model Paterson rifle. These flasks are extraordinarily rare and almost never encountered. SIZE: CONDITION: Very fine. Body of the flask retains a dark coppery color with seams that appear to be filled with black material. The attached plate shows moderate wear with a couple small dents. Back of the flask has 1 large and 2 small dents. Collar, plunger & tip are a fine brass color, as is the attached plate. Altogether, an extraordinarily rare flask. 50260-1 JR243 (10,000-15,000)
