Early 16 SS Production Dates

Unknown

I'm sure this is an old question, but are there any references that

would help approximate production dates for the SS late in '15-

early '16? Have SS Phaeton # 11157, and I'd be interested in learning

about when it was likely produced. Thought I saw some note earlier

this year that a number of the '16's were produced during 1915.

Thanks
