Иранский Хаукер "Одэкс" летит в сопровождении "Фьюри"
A formation of an Audax and a Fury, both looking decidedly foreign by the fitment of Pratt & Whitney Hornet radials. Thirty Audaxes and sixteen Furies were ordered with Hornets but the later order for thirty-four Audaxes and six Furies required Bristol Pegasus and Mercury engines respectively as the Hornet had proved troublesome.

Последним серийным вариантом стал P-38L, построено 3923 (включая 113 постройки "Vultee") с моторами V-1710-111/-113, как на P38J-25-LO, подкрыльевыми держателями для ракет HVAR и усиленными бомбодержателями. Поскольку P-38 все чаще использовались в качестве легкого бомбардировщика, на P-38J и P-38L предусмотрели возможность монтажа РЛС "Mickey" (P-38J) или прозрачной носовой части (на фото, P-38L). Экипаж обоих таких вариантов состоял из двух человек.

Jack Meaden has sent in this photo of the prototype conversion of a P-38J to a glazed nose version at Langford Lodge. It would be too much to hope it was 4300 but everything fits. It could carry two 2,000-lb bombs in place of drop tanks (or one of each) when leading formations of standard P-38s. Jack raises the question of why it was referred to as a "droop-snoot" when the nose actually turns up! Another mystery of World War Two.

The relatively few aircraft being operated by the Canadian Government in the 1920s used civil registrations in the G-Cxxx range. This Keystone Puffer, G-CYZH was one of two examples, the other being ZI. Such aircraft carried roundels but only the last two letters of the registration on the rear fuselage. The system changed when RCAF aircraft were given serial numbers.
The Puffer, illustrated here, seems to have been ignored by the encyclopaedias. The Illustrated Encyclopaedia of Aircraft had begun to lose momentum by the time the letter K was reached and Keystone only gets a resume of its aircraft other than the twin-engined bomber series which has a separate entry. The Puffer is not mentioned and it does not appear in Janes Encyclopaedia of Aviation.
Time for another Putnam?
