Yes, MB/42 would be a good choice, probably better when 7 & 9 are also compared... good observation!
** meant 1942 not 1941, 41 bands have waffenamts throughout 1941, start of 42 throughout have no WaA; the exact range this band (H-band) is observed is no suffix through the end of b-block. C-block on solid milled is the norm (no WaA in any case)
