Omega HS

Hello, everyone, is have acquired a1943 Omega HS8. My understanding is that it should have a brass alloy short lug spring bar mid case. My watch has the Correct HS8 military markings but has the 6B long lug fixed bar duralumin case . Issue no 11138 on case back matches the last 3 digits138 stamped on underside of lug. I have beesn told that matching issue numbers mean that the case back and mid case have been together since leaving the Omega factory. Anyone know why I have a6B mid cas

OP will get probably find more expertise on the Military Watch Resources forum, should he choose to join it. There are several long threads on HS↑8 cases (and fixed vs. spring bars). I'm not sure the forum members there have successfully reached a consensus, but my reading of those threads is that there are other extant examples like the OP's watch, and their existence suggests that at least some HS↑8 watches were duralumin with long lugs and fixed bars. Since the OP omitted a photo, I'll gratuitously add my own HS↑8, duralumin, short lugs, and spring bars:
