Some thoughts I had when reading:
p.56 : “these numbers lot numbers (885 to 888) would have been inserted in the “L” block and “N” blocks”. It looks like codes between D 800 and D 900 show up more randomly than usual, so maybe those cracks on Döhlen blanks appeared on other lot numbers in this range.
p.60 : 50% of forced labor when the MO plant was captured
p.61 : Mauser Werke will be wound up by a decree of November 5, 1947
P.61 : as the serials study gives 89 600 L block produced and according to the “gefertigt” figures in the table only 53 878 were "finished" in December (including rejected ones ?), it means the assembly of this block went on in January and February, no ?
p.62 : number of byf 44 is close to 690 000. If the number of rifles produced in 1944 is correct (665 000), could it be that the number of rifles produced in 1945 (not byf 44 marked) is close to 60 000 (=85 000 – (690 000-665 000)) (leaving aside production in April) ?
p.66 : the Kriegsmodell prototype dated seemingly October 1944 has barrel code 44 D 758, most byf 44 with a D7xx appear in the k block usually associated with November 1944. Isn’t that strange ? Or it shows that if this lot number had just been received and instantly machined and proofed for the prototypes, there was a 1 month lag between reception of a lot and final assembly.
p.72 : are there more rifles recorded with a barrel made at FN than this svw MB ? Could this be one of the barrels mentioned on p.169 of Vol IIa ?
p.75 : I note the 2 to 4 months duration of barrel inventories.
p.76 : in the table of barrel codes, I notice that the first half of “L” blocks have really random barrel codes (out of inventories ? because of cracks problems between 800 and 900 ?), the second half (after 40 000 L) is more homogeneous (approximately D 95x to D 1000) and corresponds to when the first Kriegsmodells appear. I also notice the mix of 2-digits “N” codes with 3-digits ones : I guess Neunkircher was doing odd things (p171 of Vol IIa).
