Hi Dave,

all I could find quickly is, according to Bowditch (page 8, section 111)

> In 1936 the first volume of Pub. No. 214 was made available; later, Pub.
No. 249 was provided for air navigators.
> Pub. No. 229, Sight Reduction Tables for Marine Navigation, has replaced
Pub. No. 214.

I would guess all three HO 249 volumes were published at the same time.
