1907 Sanderson Bayonet cipher PR

[Jaguar1970]

I have a 1907 bayonet with PR under the crown and wonder if anyone has seen or heard of this before. Its come from a very reliable source and I don't doubt its authenticity. Other markings are -
On Pommel
6 s
IN F
398

On Ricasso
1907
3 11
Sanderson

Gov't acceptance mark
Bend test mark

Inspection mark (shape)
BC
E

Second mark - possible reissue (shape)
36
E

Any ideas?

Hi, and welcome to the forum!

Very strange! It should be the Monarch's initial? And given the year a letter "G" for George?

Cheers, Ade.

Hi and thanks Ade,
Thats what I was expecting the monarchs initial, but the reigning British monarch Edward VII (r.1901-1910) died just around the manufacture of this bayonet, so thought it may mean PR -Prince Regent or something similar.
Cheers

Looks like a miss stamped ER. The cypher could have been printed on the blade some time before the date stamp. It might also have something to do with the fact that George V wasn't coronated until June 1911.
