Kia Ora
Spotted a supposed Bertin track frame on your shores that features the unusual and distinctive Capella lugs synonymous with Carlton. I'm not an expert but if it is a Carlton it could make someone's day and perhaps stay on your shores. About 57cm square according to the seller. Anyway, check the pics ...

Seller's email address: agmogridge@gmail.com ... He's asking about $400nzd but I think he'd bite for less !! I haven't had any dealings with him, and I'd suggest he's honest but not very knowledgeable about bikes. At least you could stop it from coming to Australia ;)
