Now how to get permanent battlefield1 pre-order items？

 I'm a big fan of the Battlefield series.You know that battlefield 1 has been around for six years.And the battlefield 5 has been around for four years.The cdk for battlefield 1 pre-order items are also out of print.This is a great pity for me. After my search came to nothing.I came here.Do you know how i can still get these per-order weapons(For example:The Thomson M1919)?(Permanent term edition.Not a time limit edition of VIP)
