I've had very limited luck trying to find any Reading B units available. I lost out on one that was listed on EBay for a very reasonable price. A dummy which was fine with me. Then, I lost a PRR green dummy B unit in the last 15 seconds. Looks like I ended up being the dummy!
Im not lamenting my poor Ebay bidding skills. I should have bid much higher on the Reading one.
Seems they are in high demand or just not enough units made. I’m not giving up!
