Details:

Items may need a more in depth cleaning. I do a lot of business with them and they always have well cared for gear. Everything you see in the pictures is what included this lot. I am not an operator and don't have the knowledge to fully test myself.

Not saying it won't need adjustments but, looks like a nice clean unit. Please look at all pictures closely before purchasing. I did purchase from a local operator. Photos are the best.
