Unknown weapon

[Maj-Biffy Snodgrass]

Here is another with the same style mounts, 19thc and from south Cambodia, note the very apparent lotus bud tip and hilt, a very prominent theme in Cambodia.
The basket scabbard is not likely the original but is used throughout the whole region of Thailand and Cambodia into Laos, so far i have never seen it in use in Burma though.
This one I once owned and sold many years ago. Snody
