Help locating Original or Quality Repro Dust Cover for T-89 Grenade Launcher (Knee Morter)

[Daniel]

Hello,
If you where going to attempt to make a replica there are types of fabric one is called duck cloth and the other called duck canvas that I think closely resemble the fabric used on the dust cover pictured. Those types seem to be widely available (or at least in the U.S.) You can do some research to find the best option and look at variations like thickness and weave size. Other members might have better ideas. Just trying to help.
Here is a photo for comparison of the weave type.



Regards,
Daniel

The illustration merely says the sleeve prevents entry of dust and sand.

These replicas are expensive!

Here’s one being sold sold by KiC in Taiwan. Maybe they could help source parts?
