Looking at the full res images it's hard to tell them apart.
The original liberated Rodinal formula used potassium not sodium though:

It is said the sodium version is slightly softer working.
The PaRodinal that is sold in the Phillipines uses potassium.
In the clear version of Parodinal the crystals may take months to appear but disappear again in hot weather.
IDK if the potassium version avoids the crystals,but many potassium salts are more soluble than sodium salts.
