The TR has been officially cancelled on mine too, but the other markings such as the D6E & the S on the cut-off block, are there & intact. An interesting piece of Lee Enfield history.
They could be specification rejects, but if so it took a long time for H&H to notice this...........you'd think they'd have determined that before they added all of the stamps indicating its imminent conversion into a 4T. All of the ones I've seen or heard of (only about four or five) are late rifles dated 1945 with a late serial number prefix, & I think it's more likely the cancellation of the contracts in April 1946 just occurred before they could be converted, resulting in them being returned to service as standard No4's. This would also explain the justification of barring out the TR as it indicates a 'Telescope Rifle', which these were not. I'd be interested to hear what others think though, as this is all just supposition on my part.
