Home Forums Hunting & Shooting Express Rifles and Big Bores Only Help me identify my Mark X, Whitworth or not?

I recently bought this 458 WM, always wanted one. I'm a little unsure as to it's model, the only place on the entire rifle that says Whitworth is on the rubber butt pad.
I can clearly see it's made in Yugoslavia on the rear tang, it has the barrel mounted express sights. I've attached a link to some pictures to help.
My Blue Book of Gun Values #32 makes it seem like it has to be a Whitworth but everything I read other people commenting on sounds like the receiver should be marked as such.
Thanks for any help,
Mike

IMO, it's a Whitworth.

Its a Whitworth...and a nice one at that!

Whitworth--- nice wood

Thanks for answering, maybe some did and some didn't get the receivers marked as such. Has a June 1989 date code on it.
Thanks fellas, the guy I bought it from was the son of the original owner and didn't have it listed as a Whitworth, just the Mark X wording. When I saw the wood, I fell in love.

I thought the Whitworth guns had the release in the floorplate?

Whatever it is, I wouldn’t fret; it’s a beauty. You did well.

I'm tickled with it, started some reloading today, hadn't set up my presses even though I've lived back here in Iowa for six years. With the price of ammunition it's definitely an item worth rolling your own.
It's not like I'm heading to Africa to take on the big five, it's another one of those things I always wanted to have but it will probably not see a lot of action.
On the original question about whether it's a Whitworth or not, I'm not positive either way, but if it's not, it really doesn't make any difference to me. I always look for nice wood and this one definitely was way above average.
Thanks for responding all.

Your Whitworth is an Interarms MK X They are all the same except for some things like stocks of different designs and qualities. When I first started using the Mark X in the early 80's the barrelled actions I got from Brazas Wholesale were all the same except for the magnum action like the 375 H&H which is longer.
Back then, there was a cheaper model with a non-walnut stock that was named the Viscount. Over the years the very same barrelled action was installed in several different styles of stocks and also with different company names . Remington mod 799 and 798, and Charles Daly. The Charles Daley had the floorplate release on the side like yours. Other than that, the barrelled actions have remained the same since the first barrelled action I bought from Brazas. ( $165.00)
In my opinion, they are very good rifles and like the FN Mauser they will always work ( my opinion of course)
I have a friend that was an avid Remington fan, but when he wanted ro get a 375 H&H he bought the Remington 700 with the Interarms barrelled action. He said that it was the best 375 that Remington ever made!

Your rifle is a beauty and will last forever.

PS The Whitworth is just a name ---the rifle is the Interarms MK X

I just checked out the pics - that rifle is fantastic!
And in a great caliber too!

kennymauser + 1. Near the 'end of era' as Interarms/ original Firearms International of Washington D.C., moving toward sinking into the sunset, the English born Whitworth rifles were petering out. Of Zastava manufacture and mated with wood in Manchester, more of a mix & match between "Whitworth" and the same unmarked edition as increasing.
My 458 Wnchester, Mag chambered, a beautiful rifle, but reflecting "Mark X". No real difference beyond nomenclature. My Mannlicher stocked 30-06 with Whitworth branding; same fundamental metal components quality. As noted, there existed quality differences IF construing principally stock and certain accoutrements. Express sights, hinged floorplates (cross bolt typically for heavier chamberings vs more standard trigger guard bow release), considerable stock differences. Here the net rule to me 'between Whitworth & not'... "Buy the gun 'for the build it is', not the branding!
Just my take
