Axel Pin. This pin is serialized and shows the proper machining marks for HK. Typically lighter in color then the rear top, this is also an HK tell tale. Most Axel pins that were struck were between the serial Nos 7,000 and 10,000 range â?? but few are noted. Of the 1938â??s verified (21 total), only 6 have this mark. 1938 HK serial # 9221 is marked as such, with the last 2 digits:
Rear link â?? side. Notice again, the placement of the LWaA and the color of the coupling pin.
Barrel Lug and witness marks. This area on HKs varies greatly, depending on year and variation. On this specimen, there are no barrel witness marks and the LUG area is alaphbet free:
Barrel markings. On HKs, these marks in both orientation and order MAY change. These are correct for this period of manufacture. The following photo depicts the â??gaugeâ? (as 8,84), the LWaA 2 acceptance and the 4 digit serial number. As production proceeded through HK in later years, the orientation and the proofs/serial numbers would change or be omitted. This 1938 has no witness marks, but 2 are noted as having witness marks.
Forward Breech Block. This area has several correct proofs/inspection marks â?? alongside the Military serialization. These are from this period only â?? and may be different on your Krieghoff, depending on the variation and date of production:
Firing Train. Notice the relieved firing pin. This is correct. In the next two photos, you will notice the firing pin has the military serialization, and on the opposite side of the pin lug, will also have the correct LWaA stamp. The retainer also has the correct Inspection Stage LWaA stamp. Please note both following photographs:
Underside of top rails. As noted previously, the HKâ??s were polished after being blued. Nest is the underside of the top end as it mated to the frame:
