Fairchild 24 tail wheel strut identification

[higham_jim]

'I have posted a couple pictures of tail wheel struts I need help identifing.
One has an external spring with a tubular tail wheel yoke, and mounts just like the later struts with a trailing link allowing for and aft movement with strut compression.
The other is mounted with no link, it is held rigid and allowed only to caster (no for and aft move ment) and tubular tail yoke.
I am looking to identify these if anyone can help
