EP&S Forestry Dagger

Forestry dagger, this was given to us by one of my wifes relatives, It was in poor condition, the bone/ivory handles had disintegrated and I obtained secondhand genuine celuloid replacements from Thomas M Johnson (of the reference books) website (£250) and a genuine forestry portapee from Regimentals (£250) I thought dagger it was a Nazi blade but there is some disagreement on whether this is very late war (poor materials) or post war replica, its nice anyway but obviously not worth the same as an early one.
