Details:

I do a lot of business with them and they always have well cared for gear. I am not an operator and don't have the knowledge to fully test myself. Please look at all pictures closely before purchasing. I did purchase from a local operator.

Not saying it won't need adjustments but, looks like a nice clean unit. Photos are the best. Everything you see in the pictures is what included this lot. Items may need a more in depth cleaning.
