to Wurger : I am glad you have complemented my information as the details you provided were not really featured in my resources. You are right that AJ Press books are very popular here, especially after the recent inprovement in print quality ang graphic. I buy the books in the original language, not in Czech. I have not problem reading Polish as I have been Polish books for more than thirty years now and our languages are very similar.

Sorry if I'm too late

but the both models, A1 and A2, had one bomb rack under each wing
mounted or not, used or not, it is another question.
total 10x 50#

below the wings of A1 and A2, we can see the bomb rack.
one bomb rack cover was removed.

Yes, according to the Curtiss type description all airframes had this built-in as standard.

I am interested in all sorts of manuals and technical descriptions on the P36/Hawk 75. You have any sources?

To add to above information the Curtiss manual describes an "over-load" useful weight (1.100 kgs. - as opposed to "normal" useful load - 550 kgs.). With full tanks (165 US gls.) and a cruising speed of 200 mph. at 19.000 feet, range is quoted as 1.300 sm. for the Cyclone-powered version. With the Twin Wasp, 1.200 sm. at 17.000 feet. No reserve figures are stated.
