Hello,

You have a very old-style operator that isn't made anymore. With that being said, the installation hole pattern reminds me of the 39-256B and 39-257B. This is a Rusco part and has a similar configuration. We can't make any guarantees but look over the dimensions below and see what you think. Thank you!
