Sand Blast Gun

Though the cost of a sand blast gun is within the warden budget, I submit this for HIVE input.
Sand blast guns have two main types. 1) sand hopper on the gun (rejected) 2) sand is siphon fed.
The prime wear points are nozzell and trigger.

It appears the CH nozzells are unique to CH

A number of manufacturers have copied each other and have interchangeable ceramic nozzells
