I am fairly new too, but every recent reference I have found, and advice 
given to me was simple green as a cleaning solvent.  I used plastic 
tubs, large enough to fit the sub assemblies, to thoroughly drench them 
in simple green with a spray bottle (except the motor) and scrubbed 
gently with an ultra soft bristle toothbrush.  This worked very well, 
simple green appears to be very effective.  It did take a bit of detail 
work with the brush but the varnished oils did come off with gentle 
scrubbing.  I rinsed with water and dried in the sun with a fan on it.  
I used light oil like one would do on a firearm, light coat over the 
surfaces.  I used a small paint brush as an applicator. Teletype Model

In the ball bearings, I found the old grease polymerized and it behaved 
like wax.  I used a rigid plastic pick (Rothco Gun Cleaning Pick & Brush 
Set <https://www.rothco.com/product/rothco-gun-cleaning-pick-brush-set>) 
to remove the old grease and replaced with grease from NAPA - Super Lube 
Silicone Dielectric Grease - 3 oz NCB 91003 | Buy Online - NAPA Auto 
Parts <https://www.napaonline.com/en/p/NCB91003>.  I had to disassemble 
my motor to get to the bearings in it since it squealed from time to 
time.  Getting the waxy old grease out stopped the squealing.  Not sure 
if the 35 motor has ball bearings in it, but it looks similarish to the 
motor like in my Model 28.

There are a few interfaces out there that you could use, but I ended up 
with the deramp model.  I am waiting on a DB9 to RJ11 to complete that 
setup, but it looks like deramp makes a Model 33 interface - Teletype 
RS-232 Adapter <https://deramp.com/tty_adapter.html> that may work on yours.
