I don't know how much it can help, but I have a tenor saxophone made by the same company. Same name Lark, same logo. It has a mighty sound, although it is old and needs to be restored to be properly plaid... I made some research on this company and it turned out that Lark was a very great business up to the end of the '80s, before Chinese companies started the present market invasion. So it might be that your razor too was made as a real tool, and not just to make people waste money...
