Hell if I know actually, as you said, they're a bugger to find. Lutel had something for sale, but then they got buggered over by a management switch, split in two, and now both are supposedly best avoided (though the place that got the craftsmen will hopefully get their stuff together soon). Maybe Cervenka or some other Czech maker could work, otherwise I guess it's pretty much Albion or Custom that's the way...>>15310138 The really stupidly big ones are most likely parade swords
Nope, they were intended for heavy cavalry troopers to actually used. Quite a bit of politics behind them though... Swedish cavalry wasn't doing very well in Pommern in the war of 1757-62, and their m/1739 sword (pic) became the scapegoat (I suspect due to someone wanting to replace the half a century old style with the latest fashion, ie pallasches). IIRC the complaints where that the m/1739 was to dainty and weak (sure, it might be over three pounds, but who cares), so the new pallach was made bigger. Considerably bigger. I don't have any data for the m/1761 directly, but the sign in the Army Museum says the m/1773 (middle in the above pic) was an entire kilogram lighter, and that one sits at around 1.6kg...
It's unclear if any of the m/1761 ever made it to the front before the war in question ended, but afterwards they were quickly hidden away in the armouries before being scrapped altogether.
So, yes, they made a 5.7lbs onehander for fighting. It just wasn't a good idea.
