Con-Space CSI-2100 Communications Command Module This came from a city fire department. I haven't been able to test it, but it is in good used condition. At the time of this listing, I have a quantity of these black modules and so you may not receive the exact one shown in the pictures, but they are all pretty much the same in condition. I have some grey modules of the same model listed as well as some Con-Space cable and talk boxes so please take a look at my other listings. L3-1 80111258
