In 1924 the company founded
Huff Daland Dusters, which used Huff-Daland airplanes for agricurtular work, mostly dusting. In 1928 it split and later became Delta Airlines.
In 1928 the company bought the
Loening Aeronautical Engineering Corp. and continued to develop flying boats in this new division, which was transfered to Bristol. (former Loening employees started new company in the original factory, called Grumman Aircraft Engineering Corp.)
In 1929 HD became part of the Curtiss-Wright group and was dissolved in 1932 due to no new orders.
LB meant Light Bomber and it was USAAC cathegory, I found no mention of LB-15 or LB-16 being assigned to any comany.
