Help! need a 1680 rep backcase

[aeromatic]

13 is really unlucky for me so far this year ! ,i sent my 1680 rep backcase to be engraved (tudor markings) and its got lost on the return post now i dont have a backcase for my blue snowflake sub!

If anyone has a 1680 replica backcase let me know i got it from trusty im not sure if a 5513 rep backcase fits i know that a 6538 cartel backcase does not fit even though they are both bubble backs

my blueflake case is the 2846 trusty 1680 rep

 

Thanks in advance !
