Recently picked up this Oberndorf Mauser Model M in 30-06. from Reliable.. They were asking too much for it, but I negotiated with the actual owner of the rifle and managed to get the price down to something a bit more reasonable.
I have a Model M, also in 30-06, with a serial number only four numbers later. (So probably made the same day in 1922 or 1923.) However, that one has a more conventional Lyman #35 sight. (See the last photo.) The "new" Model M, has a receiver peep sight that also mounts on the bolt stop like the Lyman #35, (no drilling and tapping), but it does not resemble the Lyman in any other way. I can find no manufacturer's markings on it. There is also no indication that any open rear sight was ever installed, so it may be a factory installation. I know Mauser kept a supply of Lyman sights on hand for installation, per customer request, but this sight is different.
Has anyone ever seen this particular peep sight? I have not.
As an unexpected bonus, it came with a brass cleaning rod stored in the buttstock. Hard to remove, it seems to have been stuck in there for quite some time. Each section of the 5-piece rod has a number, and it is the correct length for the short barrel.
Another interesting feature is the factory-installed steel recoil cross-bolt.
The rifle is in overall VG+ condition with great wood and an excellent bore.
