Hurd Double Hung upper window lower sash seal

Question

I need a replacement for Hurd Double Hung upper window lower sash seal. This seal is kerf mounted ... but instead of single circle bulb, it looks like a figure 8. I think it may just be a crushed circle bulb. It is in upper window but slides against lower window.

I agree, that's just a round bulb that's been crushed down. We don't have an exact match for this, but I'm reminded of our 58-053. Look this over and let me know if this could work as a replacement.
