This is a senior administrative officer's sword, probably either a surgeon or an apothecary, viz the twin-headed serpent on the guard. The little dolphin head at the end of the knuckle bow by the pommel indicates the naval branch of service. The mounts are ormolu and the grip is ebony.

This is a classic Ernst Pack dress bayonet, with no maker's mark, but the 'signature' screw bolts which no other maker used. The original owner must have been in a heavy artillery unit, as suggested by the obverse blade etching. These weapons were normally only worn when off duty, but in uniform.

This sword, dating from 1805-09, would have been carried by an Inspecteur aux (or 'des') Revues (the equivalent of Commissary in the British Army), responsible for pay, provisions (hence the ears of wheat on the guard and knuckle bow) and the depot system. Before this, they simply carried an ordinary infantry sword. The sword is rare.

This die-struck badge was awarded by the Weimar Republic to WW1 tank crews who had served in three assaults or been wounded in the course of one. The soldier had to apply for the badge and, once he had received the award document, would privately purchase the badge. Sepp Dietrich, commander of the LAH, wore this in 1940 photos.

Regarding the regiment, the Grenadiers had a very specific gorget with multiple pierce work on both wings, the Scots Guards normally had '3rd Guards' engraved on both sides at the tips, therefore, by elimination, this is almost certainly a Coldstream Guards example. The Dighton watercolours of the period appear to confirm this.
