Hi ndm - unfortunately it's not Open data (RM "services near me") therefore I have not changed the reference itself...still requires survey.

Hello - W2 50 is mapped in the expected location at Praed Street - is the box at Chepstow Road W2 56? (Probably a mistake by original mapper.)

Hi Phil - your description says CH60 231 but the reference has been entered as CH60 230, which already exists elsewhere. I can't quite read the photo to double-check, but would expect 231 here.

Hi Chris - yes 8089 should be Church Road, Wyverstone - sorry to add confusion! 8083 is the one. Thanks.

IP14 8089 expected here and box 8084 already mapped elsewhere. Is this another case where RM have shown the wrong box number?

CP7D refers to the style of "Collection Plate".
The reference should be on the line above, against the label "Postbox number".
Is it possible to double-check, please?

RM and other data suggests Thornton Road near Borough Road junction, as does the photo dated July 2020.
