Vintage Singer 66/99 sewing machine handcrank vs OKBY Chinese copy comparison and modification.

A comparison of the quality and differences between an original Singer 66/99 antique sewing machine handcrank and a cheaper OKBY Chinese reproduction one from Amazon. I also modified the Chinese one to eliminate the slackness in the handle. As a disclaimer, please note this particular brand (OKBY) of handcrank did fit my Singer 99. I cannot confirm that this will be the case with other similiar models sold on Amazon. I am not being sponsored by OKBY nor is this a personal recommendation to buy one, this is just my personal opinion of this product.
