This is an perfect example of the Swiss Model 1943 Officer's Dagger, complete with the original scabbard and red / white portepee. As with other examples we have seen, it is marked on the blade ricasso with serial number 17592, with maker Elsener Schwyz marked on the other side.
By the historical information this number dates to the early production period, approximately late 1944.
The dagger is in perfect "MINT" condition, near impossible to upgrade. 
A rear item for a collection !
