replacement bulb seal

Hi, Attached are a couple of pictures of some weatherstripping I'd like to replace. The house was built in 1988/89, and we purchased it in 2000. We have no idea what brand the windows are, but they might be Pella's. They have aluminium cladding and are somewhat similar to some Pella's we have in an addition we built in 2001.The base appears to be 0.230 inches wide and 0.037 thick. With the bulb squished back into what I think it's original shape is, it has an overall height of about 0.300 to 0.320 high and 0.330 to 0.350 wide. Thanks,
