A spate of reproduction AVRO ARP insignia has recently been placed on eBay. The seller uses several accounts to sell similar items (always a good clue to fake items being fobbed off). There's no known photos of any AVRO ARP badges except for the known metal and enamel badge. It appears these reproductions copy some elements of this badge but they do not follow the font exactly (another good clue to them being fake).
News about interesting insignia, ARP related info and period photos that turn up.
