I realized after reading a post that we had done our CBP form# 4457 wrong last year (sometimes ignorance is bliss). Luckily it went fine with SAPS. As it is quite a distance to the nearest border or international airport, I was wondering if there is a alternative to the 4457 form. Someone that went several years ago said that they had gone to the police station and had some papers filled out but didn't remember what it was for. Is there something that can be used as proof of ownership for the guns rather than the CBP form# 4457?
