Here we have three gearboxes, and one motor all are listed as spares or repairs. 

One is a V2 Classic Army, which came out of a recently acquired M16, and was working fine until then, however since I have no way of testing it now, it is being sold as spares or repairs. 

One unknown brand of V2  gearbox, I can't remember much about this one to be honest, might have been out of an older G&P gun, but I can't be sure, again, it's spares or repairs. 

One Army Armament gearbox from an L85A1, I know nothing about this one, as it was included as parts with a L85 I recently acquired for a project, again, spares or repairs.  

One Classic Army motor, came out of a recently acquired M16 from the first description above gearbox, worked fine, but is been sold as spares or repairs, parts only, as I can't honestly re-test it. 

Any questions, please ask, I will get back to you asap, working shifts allowing. 

Price is posted to your door.
