Sorry Dave .....I had a senior moment with my last post ....... I have reread your post about the two spade terminals, and you are right, The Atmo does have that type of starter.
One of the spade terminals is the feed to the solenoid when you turn the key to the start position.
The other one is connected to one of the big nut connectors .... the one that is connected directly to the actual starter which becomes live when the solenoid is engaged and the engine is cranking. This second wire goes back to"effectively" bypass a series resistor which is normally in circuit once the engine has stopped cranking and the engine is running. The purpose of this is to boost the EHT spark voltage to assist starting.
Values are not exact, but this is the principle......... the coils normal working voltage is 10v so this is why there is a series resistor to drop the 12v to 10v for normal running. When the starter is energized, that same starter voltage is fed back directly across the 10v coil, thus the coil now produces around 20% more EHT, once the engine starts and you release the key, that voltage is now removed from the coil which is running at its normal 10v. Don't worry the coil is designed to cope with the over voltage for short periods of time.
If it is difficult to get the correct starter, I think Paul Goldsmiths suggestion of a refurb is the way I would go.
I hope this helps.
