Vintage SAVINELLI FREEHAND PIPE - Not sure of Model - Snake Mark - Old

Vintage freehand Savinelli pipe. Marked Made in Italy with snake on mouthpiece and on base. Also marked Italy on bottom stem. I do not see any other markings. Although they may be there - the pipe is dirty with soot. I was able to rub some off - I am reluctant to clean for fear of damaging the wood.
It looks like an autograph but I am not sure.
Nice condition except as noted above. Should be cleaned.
Please see my other listings.
Good luck.
