Only Mike, Bruce or Craig could tinker with your account, though I think you reached the 3 posts that most restrictions are lifted.
While both of these rifles are common maker-dates, probably two of the top 10, the bcd/43 can be interesting. You took a picture out of the stock; did you take pictures of the markings on the barrel? Most often they have Ruhrstahl (avk, & e/13 barrels) barrels or FN (ch or waffenamt e/140 barrels) but not always, what is the code on the barrel, or the waffenamt? This will tell who made the barrel; Gustloff did start making their own barrels in 1943, though typically later in 1943 and most were rejects, usually used in commercial production until 1944, when most show up.
Anyway, if you can post some pictures of the rifles markings, we probably can tell you something of the rifles. Welcome to the forum!
