A Brigade of Guards Side Drum (a replica?)

[kswong]

Hi everyone,

 

Recently, I came across this military snare drum on this internet.  Would like to seek some professional collectors' opinions on this drum, why the drum seems to be pre 1960s but the front battle honour included Falkland Island 1982?
