Searching for WFCM-Wood French Casement

A quick learner says:
I have Marvin WFCM-Wood French Casement units, installed about 20 years ago by the former owner. I look for the hardware, especially the locking mechanism, including if possible the 'finger'.
Thank you

Hello, thanks for posting! We would be happy to help you identify some replacement hardware. However, we will need to see clear images of the parts you are looking to replace, preferably removed from the window. For operators, we need to see the entire assembly, including the link arms.
