Anderson window crank

I'm really not sure. The year alone doesn't really narrow it down. I see you were looking at our 39-094. I would carefully compare our pictures to your hardware, especially the measurements. Are they the same? If not, how do they differ? We also have the 39-150 and 39-331. Pictures would be a huge help, if you are able to figure that out. One reason pictures fail to upload is because their file size is too large for our site to process.
