Here's the last to Hollenbeck patents assigned to Baker..
at least the last two that I have found...of about 20 or 21 Hollenbeck patents, only three are assigned to Baker...505794 is unusual in that it's assigned to Syracuse Arms although Frank still resided in Batavia (7/25/92). Then on June 10, 1893 he appears in Syracuse and that patent [519126]is assigned also to Syracuse...
.
So...June 19, 1886 he lived in Syracuse, Jan 15, 1891 he's in Batavia 'til at least 7/25/92, then June 10, 1893 he's back in Syracuse
