George IV Infantry sword variant.

[kronckew]

Thanks, George IV ruled 1820-1830 and was succeeded by Queen Victoria, so the brass cypher could only be from that decade. the blade, however, looks more like the late 18 to early 19c you mentioned. I'm wondering if the patination pattern corresponds to remnants of bluing. Ah, well will find out in a few days.

This was the beginning of standardisation of sword patterns, started in 1796, but still a bit flexible. Officers especially (probably exclusively) were still able to be 'flexible' as they were (and still are) expected to buy their own swords in the UK, and in the USA.

I'd guess this was a personally liked blade, possibly an heirloom passed down from a martial daddy that was rehilted to fit in with his regiment. The std. pipe back blade was not all that popular as it wasn't terribly good at slashing, being later replaced by the straighter fullered blade that carried on thru the Victorian era. the troops using pipe backs in crime complained they flexed on Russian greatcoats rather than penetrated. The officer that carried this one probably preferred the cut to the thrust.
