So the stag on my GTR has developed a crack. I plan on sending it to Randall but wondered if they choose to repair, not replace the stag how noticeable the repair is typically. Especially hoping to hear from someone who has been down this road.
Thanks in advance.

Is it a true crack or a check line?

Randalls warranty is excellent. I assume the handle will be replaced. Repairing a crack so its unnoticeable is too painstaking. Ive never heard of any manufacturer repairing handles, they usually replace them. Some private craftsmen fill the cracks with the epoxy , matching the color. Its a very tedious task and does not guarantee that the handle will not crack again

A friend of mine had a Sambar horn (not a Randall, Puma Nicker) crack when he flew on a plane to the desert in winter. He lived in the north near the sea. I think it was caused by the sudden change in humidity and temperature - from 0 C to +45 C, and from high humidity to near zero. Puma just replaced the handle
