Further to this post: The harp I am presently working on is a CR45E Oscar Schmidt Electric. It was just played out from long use and needed all new felts. It was more economical to buy a 21 chord conversion kit from Janet Davis Music. The conversion kit was excellent. However I need an E Major chord Bar which is not available and so ordered the felt strip to cut one. The strip was narrow and inferior. I sold this harp a number of years ago and it came with the E Major chord substituted for EMajor 7th. Conversion kit also came with Emajor 7th. Also ordered an Oscar Schmidt string set which was missing one string. Anyhow, Thanks for all advise. It is appreciated. I am on the East Coast of Canada. Autoharp parts are very hard to obtain in this area.
