The oil filter's origin appears (if I am reading between the line correctly) to be an AC OF-100
STC 4178NM lists the 6A-150-B3 in the AML. No aircraft is designated.
The (Stinson) 337 I was given along with the STC mentions some mumbo jumbo about The Sky Companies and Turbo Tech
Report Of-100 ( no copy of that and can't google it) more or less ok so far because this is for the Franklin
and then:
some crap about STC SA637NM and AC OF-104 and Sea Plane Flying Inc.. which stc has nothing to do with oil filters
and Installation Instructions SF 20699.
What a lot of tuna.
Lil Red Aero meantime is the holder of the STC 4178NM... which lists stinsons and some others with franklins
but nothing about bellancas.
Whole load of crap.. and $300 worth of oily parts in a bag. Which I haven't looked at closely yet
( too busy) but appears to me to be a $ 10 AC spin on oil filter adapter, some hose, and the oil pressure relief
housing from a franklin.
I mentioned the tuna right ?
