You can faintly see the 5 Z 204, I can't tell if there are any other Numbers. It does fit the Model T exhaust nut. $37.00 with free shipping. I believe at least 1/2 the cost will be taken up by shipping. Web site taking uploads of pictures at this point. Will try again tomarrow.
Sold to S. Linney pending payment, sorry for the late post, it was a long night. Thanks MTFCA!
