It is kerf set. the kerf edge approximates 1/4 inch long and 1/16 thick.
Half round "bubble" is 1/4 inch wide, 1/8 inch high.
the "wing" is approx 3/8 in length.
I know you may not have an exact match but do you have something that would be similar.
This is the weather striping that is on the sash unit not the frame.
I do not have an adequate photo of the installed part since almost all of it is deteriorated.
Thanks
