Curtiss P-1 Hawk

On 7 March 1925, Curtiss was awarded a contract for 15 production examples of the XPW-8B as the P-1, this being the first fighter to which the company assigned the name Hawk. Externally similar to the XPW-8B, the P-1 was of mixed construction with wooden wings and steel-tube fuselage with fabric skinning, and was powered by a 435hp Curtiss V-1150-1 12-cylinder water-cooled engine. The final five aircraft were completed as P-2s, three of these later being converted to P-1A standards. Follow-on contracts were placed on 9 September 1925 for 25 P-1As (which had a 7.62cm longer fuselage); on 17 August 1926 for 25 P-1Bs (with V-1150-3 engine, larger wheels and modified radiator), and on 3 October 1928 for 33 P-1Cs (with wheel brakes). All these sub-types carried an armament of two 7.62mm guns. In the meantime, the USAAC had ordered advanced trainers utilising the same airframe, these comprising 35 AT-4s (180hp Wright V-720), five AT-5s and 31 AT-5As (220hp Wright R-790), and, in 1929, these were re-engined with the V-1150-3, all 35 AT-4s becoming P-1Ds and four AT-5s and 24 AT-5As becoming P-1Es and P-1Fs respectively. These conversions were essentially similar to the P-1B apart from having only one gun. Four P-1s were supplied to Bolivia, one P-1A went to Japan, and eight P-1As and eight P-1Bs were supplied to Chile.

I have a photo of Jimmy Doolittle standing in front of the lower pictured aircraft wearing Curtiss coveralls. The photo is autographed to "Sally, Billy, and Skip" at the bottom. WW

I am looking for scale drawings of a Curtiss P-1. If you know of any such drawings please let me know.

Do you have any comments about this aircraft ?
