A quick scan through the Air-Britain Big Book (BCARs 1919 - 1999) shows the following:
G-AGLZ to VH-EAU
G-AGMD to VH-EAS
G-AGML to VH-EAT
G-AHBW to VH-EAV
A check through the Lancastrian aircraft registration documents on the CAA G-INFO site is in total agreement.
There is no evidence of foreign registration on the documents for G-AGLS, G-AGLT, G-AGLW or G-AGLY.
