[Collins] 270G-3 speaker - retaining springs for trim strips on front of cabinet - source needed

[k2dp at charter.net]

Hi all,

Am in the process of refurbishing a 270G-3 speaker for my 75A-4.  One of the retaining springs which holds the black trim strips in place on the front of the speaker cabinet has broken. Does anyone know of a source for these springs which fit inside of the back of the trim strip and push through the hole in the cabinet. The trim strips cover the screws which hold the speaker, speaker grill and backing board in place.

Thanks in advance for your help.
