Details:

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

Everything you see in the pictures is what included this lot. Not saying it won't need adjustments but, looks like a nice clean unit. Items may need a more in depth cleaning. I did purchase from a local operator.
