Need info on Sensenich 90HSP90

[Fehrfam]

Propeller has been in family for many decades. Looking for any info available on it. Markings say Sensenich Bros, Letitz, Pa, Model 90HSP90, Ser No 65087 HP 160 RPm 1850

OK, here’s what I can tell you (others on this forum may be able to add further detail)
The serial number format dates it to between 1932 and 1943.
The design number indicates 90” diameter, 90” pitch and an integral spinner (any chance of a photo of the whole propeller?)
The designation for a 160hp engine rated at 1850rpm would be consistent with the Kinner R-5 engine.

All of this information suggests to me that the propeller is from a Ryan PT-22.
