What a mess Dean
The arms of the cocking rods are visible protruding from the knuckle, and can be used to cock the hammers even with the barrels in place
You can't fit a wrench, so use a long screwdriver (for leverage) with a thin blade with a layer of electrical tape. Use the other arm to lever DOWN the opposite arm
The R arm is down and the R hammer cocked. You will feel and hear a distinct 'click' and it does take some force. Then cock the L hammer.
If you can't lever the cocking arm at all, it's time for a Smith specialist.
Once the hammers are cocked, remove the barrels.
There might be a 'CHAMBER 2 7/8' (not the later football) mark on the flats
There are disassembly and reassembly instructions on the FAQs, including removing the sideplates.

The lifter needs to be down when reattaching the sideplates
and be sure the hammers are cocked to reattach the sideplates
AND to reattach the FE
Please let us know how it goes.

NOT remove the trigger plate if you've never replaced the trigger plate - angels fear to tread the innards of Smith guns
