I think I have seen the advert for that M03 with a .458 Lott, .375 H&H and a .338 Win Mag barrels. Aout $15,000 for a M03, WOW! Nice wood and probably engraving is my guess.

A lot of second hand firearms seem so highly priced to me nowadays, I must be loosing touch with the market. Or the internet listings are unrealistic?
