Hi Asomotif
,
the tang is not visible at the pommel. The pommel end of the antler is capped with a nickel 'plate'. The distance from the crossguard to the pommel is exactly 5" (127mm)
According to my information the tang on a F/S blade is
4 11/16 " + 3/16" (the 3/16" would have been threaded into the pommel nut) which would make the total length 4 14/16" (124mm)
I can only assume that the tang does indeed run through the entire handle and is (invisibly) threaded to the pommel cap. Will try and get a strong magnet to test this.
Also I forgot to mention....if the makers "Crookes" ceased manufacturing knives in 1915.....this F/S "copy" blade preceeds the FS dagger by nearly 30 years
Unless, during WW2 they were 'enlisted' to produce military blades?
