Question

I am trying to match the single hung MI 455 series.
I was told to contact you from our MI representative.

I agree, it looks like either our 90-005 or 90-009. Unfortunately, I can't tell which one based on these pictures. The difference is in their tongue. Look at the image below and see which would be a better match.
