Just stumbled across these sights coming up at auction tomorrow (10th Feb) in the UK.
These are not something I've seen or noticed before as my interest has been 4Ts and later. I've no connections or interests in the item but they seem to be rare by all accounts and may be of interest to SMLE & sniper collectors on here.
