Does anyone know the maker of this No. 80 Mk IIIA fuze I have please? Back-to-back Rs.
Thanks, Graeme

Interesting fuze.
The only RR back to back monograms I know are Reuter & Reynolds also Richard Rinker German grenade maker.
I have no references that these people made fuzes or No80. It must be British?

RR is not the make but a Romanian acceptance mark.

Thanks Hoeksel. Unusual. Do you know what ordnance Romania might have used these fuzes on pre-WW1? (Given the fuze thread is 2” x 14 TPI Whitworth.) And how such a fuze ended up in Australia? Mk IIIA fuzes date from about 1911-1912
