Details:

I am not an operator and don't have the knowledge to fully test myself. Photos are the best. Not saying it won't need adjustments but, looks like a nice clean unit. I do a lot of business with them and they always have well cared for gear.

I did purchase from a local operator. Everything you see in the pictures is what included this lot. Items may need a more in depth cleaning. Please look at all pictures closely before purchasing.
