As a matter of fact I purchased to sets of parts off E-Bay and both had hammer plunger's with out holes so for me they are useless I have a hard time putting in the one with holes.Sometimes the spring and the Plunger go flying.
Any way did you notice the high bidder?Why does he want them?
Who knows? Alden does buy stuff cheap and then resells it. Overall he is not too bad of a guy,BUT, he does buy from some questionable people on some of the other sites so you really have to watch what you are buying fom him.
The good side is usually you can out bid him, without breaking he bank, if you really want something. Like I said, he buys cheap to resell. Unlike RBA, buying post-war T3 bands at 28 bucks a pop, only to try to sell them at 50 bucks each down the line
