[78-L] Stylus for RCA Home Recording Disc

[Sammy Jones]

Playing an RCA Home Recording disc with an Eddie Cantor show from December 
1935 tonight.  The largest stylus I have is a 3.25 mil Stanton TE.  The 
sound is actually not too bad with some EQ tweaking.  The disc is 12", has 
and orange and black RCA Victor star label, and has H-500-3 stamped in the 
run-out area.

Here's a photo:

I'm assuming I need to get a 4 or 5 mil stylus to play this correctly. 
Anyone care to share recommendations on success or failure in transferring 
these things with variouis stylus sizes?  I need some recommendations before 
I drop 165 bucks for a specialty stylus.

Thanks,
Sammy Jones
