Square tube action rails for Steinway M

[Greg Newell]

Has anyone ever seen square tube rails on an M? I’m replacing part because
of Vertigris but I spotted this square brass rail tube with a square .. um
dowel inside. It’s not soldered to the frame but rather screwed in at the
ends. I’m thinking I’m gonna replace it but I’m just wondering if anyone has
ever seen this before.
