This is one very nice Commercial Mauser that remains nearly as honest as it did 87 years ago. This very piece is listed in the Mauser book as a Magnum Square Bridge Model A in 404. Relative Type A, the 404 and the 250-3000 are considered the hardest chambering's to find. Several serious Mauser cranks have handled this gun and most will comment it is one of the best Magnum Action 404 they have seen relative overall condition. This is nice stuff from a classic era and it lived a guarded life in a great collection of big bores since 1983. We also have a Type A 250-3000 Kurz that is absolutely outstanding and appears unfired.
