Great Forum and THANK YOU hugely to all who have contributed.

I found in a Maryland junk pile my Sigma SDM-18...wooden burn stamp inside Saying Korean.

I rebuilt the headstock..reattaching it to the neck with some walnut (I am restoration specialist and this bit of luthiership appealed to me)

I loved it!! deep abiding love. I play for myself.

Now...from one of the inspired messages I just found here, I machined a perfect replica of the Saddle from 1/8"Brass..old soft brass..
I lifted the action a scant hair in the process.

And it sounds like a clarion to all other dreadnoughts!

Great advice!
Thanks again to all who post here.

If any would like a picture of the improvements I will happily send them on..nycfarmboy2003@yahoo.com
