I'd just like to apologize for being one of the lurkers. I'm not a very talkative person and find it difficult to interact with others, even those I know well. I am guilty of hopping on here to ask for advice or occasionally comment on a subject under discussion. I do hope that my reticence isn't mistaken for being one of the negative lurkers. Your friendliness and willingness to share your knowledge and experience has been invaluable to me as I have acquired and restored my vintage machines. For that I am very grateful.
