Value? 505 Gibbs H Dumoulin & Fils-Milmort-Liege-Made in Belgium

It all depends on the Action of the rifle. I suspect this one is the Brevex400 as it has a solid side wall and is drilled on the front reciever to allow loading. I would say this rifle if it functions well and shoots straight is worth the price of any well made custom gun. I have a few such DG rifles that are not collectors grade but good honest working guns that were made with a bit more love that the run of the mill CZ. $8k minimum. I have a Few Belgium made rifles - they are all well made.

I may be wrong, but in my opinion it is not a Brevex action.

I appreciate everyone’s responses. My father and I went on Safari back in 2008 in Tanzania where we spent a little over a month. Memories and experiences that will stay with me for a lifetime. The rifle belonged to the gentleman who we hunted with. He was of British Descent and had been organizing hunts for many decades. My father had it imported through a FFL. Upon his passing he left it to me. As I may never return to experience Africa in that capacity again; I have no need for a rifle of that caliber. I have several rifles that had memories including my Kreighoff .470 which was my rifle of choice. But I also had a .458 Lott which was my go to choice. The .505 is unique in its own way and it is great to look at. But I would feel better if it could make its way into the hands of someone who will appreciate not only its beauty but something someone would take back to Africa on a Safari of their own.

Thank for sharing the additional information, the rifle does definitely have an interesting story. It’s great to hear you want to ensure it returns to Africa.

I think even an expert (which I am not) would have trouble putting a price on it as it’s very unique. I have not seen a Dumoulin like it. Three especially interesting points (at least to me) is the magazine locking mechanism and the lack of sling attachment points and 22” barrel. One of the more interesting DG rifles I have seen in a long time.

The caliber is a double edged sword, it’s worth more because it’s a 505, but less people are in the market for that caliber. All that being said I would hazard a guess it’s not worth less than 10k, probably more. If the gentleman your father got it from was a hunter of note, that could also be a factor.

Would love to hear your insights @buckstix on how you recognise a Brevex action.

Only about 450 brevex actions are known to have been produced. Here are some basic indicators of a brevex action (first pic) - but the most reliable indicator is the factory stamping on the bottom of the action (second pic) factory serial number, brevex BV logo, M stamp - M300 is 375 H&H bolt face, M400 is the 416 Rigby/460 Wby/505 Gibbs/similar large bolt face, M500 (very rare) has been seen in only 2 rifles in 505 Gibbs cal. - there have been occasions where the factory stamping has been removed, so other factors must be verified, i.e. trigger-guard hole spacing. My information is based on observations from the 18 rifles in my brevex collection. (last pic) - and I am actively looking to add number 19 to my collection.
