Amperite 6C5 time delay relay

[W2INR]

I am looking for the pin out on this relay. It is the Old Buzzard amperite 6C5 delay relay.

Thanks

Gar..
page 1053 , 1962 Radio Master.
6C5, octal, 5 sec. delay, +/- 2 seconds at 20 deg. C.

"standard radio octal" pin out. - pins 2 and 3 heater, 6.3vac;
pins 5 and 7 are the contacts, normally closedin a 6C5.   If the contacts were normally open it would be a 6N05. Interesting.
Also no connections are shown on pins 1,4,6 and 8.

Also a note on breaking DC current as follows:
"When relay contacts open DC current above 50 volts, a condenser with a resistor in series with the condenser must be connected across the contacts. 
Following values approximate."

"0. to 0.5 amps , 115 vac req's. 0.1uf.;  230 v req's 0.25uf.
0.5 to 1.5 amps, 115 vac - .25uf; 230 v - .25uf.
1.5 to 3 amps,  50 vac - 0.25; 115v - 0.5 uf and 230v -0.5uf

Not mention of an accompaning series resistor value.
Minature 9 pins are accompanied by a "T" in nomenclature, e.g., 6N05T.  Standard pin out for the 9 pin minatures ; pin 1 and 6 heaters and pin 8/9 stationary contact, pin 3/4 moving contact.

too bad it isn't a normally open Ry; you''ll have to be creative.
Well, probably TMI

Oh,yeah, just noticed a whole other page devoted to Amperite relays.

 Standard 2 to 10 second models including the 6C5, contacts rated at 3 amps AC / 115 vac ; 1 amp AC / 220 vac. 

DC voltage breakdown 250 v contact to contact.
DC voltage breakdown 500 v heater to contact.

I would venture to guess the purpose of the resistor/capacitor network is to absorb the inductive kick  that would cause the contacts to spark on break, when switching DC working into an inductive load.  Wouldn't a reverse-polarity diode placed in parallel with the load accomplish the same thing?  That network sounds very similar to the key-click filter commonly used for for cathode keyed transmitters.
