What we have as far as I can ascertain is a Pattern 1860 Yataghan bayonet originally designed for the Pattern 1856 rifle. This particular bayonet being converted in the 1890's to be used as a shortened bayonet for the boy's of the cadet force.
The original ricasso marks have unfortunately been mainly removed leaving only later conversion dates. The crown 58E is the Enfield inspectors stamp.
Many Patt 1860's and earlier Yataghan bayonets had a bushed muzzle ring fitted in the 1870's to allow fitment to the Martini Henry rifles.
No idea what the W and GT signify??
The original Patt 1860 was considerably longer and obviously the scabbards were cut down to suit.
