Hello all, I bought a Consew 227r in NY and imported it into Nicaragua. Customs officials don't believe that I paid $400 for the machine and have charged me $500 more. Now they want me to pay an additional $2500 because I have an industrial sewing machine. I need to show proof that the machine is old but can't find any paperwork stating the date of manufacture.. I think its around 1960's but how can I prove it. I have searched in the manual but to no avail. I don't have an electronic transaction so this is leading to more problems for me. Basically it comes down to he said she said and I don't have a leg to stand on. Help??? Thanks in advance.
