It has now been established that the H.E. bombs Wgr. 38 and Wgr. 39 (described in Pamphlet No. 11) designed to burst in the air after impact, have been converted to nor-mal H.E. bombs. The coverted Bombs are designated" 38 umg." and "39 umg." respecti-vely. These bombs range the same as the standard H.E. bomb "Wgr. 34" described in Pamphlet No. 6, page 9.
