How much can I disclose?

From this schematic ( I hope it is readable ), I can determine R total as:

1 / 14 + 1 / 21 = 1 / .119 = 8.4 Ohms. The current in this
circuit is:

I = 8 / 8.4 = 952 mA (800 mA actual reading).

Question: From this data, can I determine the available current in the
secondary?
952 mA is the apparent current but, the actual available secondary current
is much, much, higher.

No.....
The 'short circuit' current is much higher than the maximum load current but
cannot be utilised.
To find the safe maximum load cuurent, measure the off-load output voltage
and gradually load the output untill the the voltage is at 85% of the off
load voltage value. The load current can be measured now. This is the
approximate maximum safe load condition. Applying a load that produces more
current drawn from the transformer will cause the the winding to overheat
and meltdown will result in shorted turns and a useless transformer.
