The Cradle was not used for different size coal... the early versions of the cradle (which housed the auto-igniter) just plain sucked. but this was a company at the time that was pretty good and I think they shipped new cradles out on many occasions (don't expect that kind of service or integrity today!), Its a rice burner and always has been (no cradle is going change that, the poster is misinformed because he is not a member at NepaCrossroads
I should add that this cradle was given for free because of its flawed function (the poster most likely did not pay the $39.95 for it at the time). He should be paying you because you have to install the re-called item that he never did!
Im not sure what these cost brand new now but it cant be much more than he is asking for this dinosaur
