I picked these up from MBK. IMHO as a rivet counter these have the BLMA F/E unit grabs beat, they lack the flatness that is found with the BLMA parts. Which means I dont have to load it up with paint to make it "round". Unfortunately, unless ACME Labs makes them (ie. Me), I still need the uncoupling lever among other parts from the BLMA set.
