Engine emblem ??

[bandmngr]

Hello,
I was a volunteer at one time but not any longer. While tearing down a chimney in Dyersburg,TN, I came across this emblem. It is an intertwined F & S with the number 8 on it. I have searched everywhere and cannot find any info on it. I will add the pics to my profile , if that is possible. If anyone has any info it would be greatly appreciated.

Thanks for the link. I believe this is what I have. I have sent off emails with pics to them. I'll post when I have an answer.
