In regards to your query about the Profile guitar.

I have…Sears Canada is the culpurt! These are just middle class generic models, tons were sold between the early 70’s late 80’s. I myself own a Profile acoustic model PA-30, and as like you …I goolged my model with no results. My wife was our savior, the guitar was bought new in the seventies by her grand-father. Now as for parts, I’ve been lucky. I only ever needed to change the headnut…for string height issues. The model is a copy of the burntwood model of the 1932 Gibson. As for new parts, all I suggest is buy used, working or not and start stripping.

Hope this sheds some light for you.
All the Best
