Help identify these parts

A quick learner from salt lake city utah says:
These are glazing and retaining strips off my circa 1986 aluminum frame double glazed horizontal slider windows. A big one on the west facing wall is deteriorating and needs fixing. I found the name Linford and 1985 etched into the spacer between the panes of glass if that helps.

This looks very old, and it's hard to find original glazing strips in this situation. You may want to consider our 55-090 and 55-071-6 as possible substitutes.
