Jouef HO/OO Cargowaggons - Coupling assembly springs

[inoffapost]

During a root about in some stored boxes I came across a batch of these I had forgotten about - all brand new too!

However, a couple are missing the small moveable NEM coupling retaining springs that attach the assembly to the wagon chassis.

Does anyone have a clue where I might source some of these fragile things? I'd like to have these wagons operational for a cargo warehouse element I'm building on the layout.

Any help appreciated.

Thanx
