Well, I bought this item vietnam ww2 telephone radio receiver and transmitter US military | eBay . I did ask for pictures of the insides, but received more reply. Now it is here, and it appears it was a mock-up. Since the seller claimed Vietnam and it had a suffix M, I thought it may be a solid state version. Well, there is nothing inside but weights to simulate a real BC-611(X). The antenna is just made out of a piece of rubber. Anyone have any other info before I give the seller negative feedback, which I hardly ever do. I emailed him about it days ago but he did not have the courtesy to even reply. 73 – Mike
