Raoul,,the only difference is the the 392 being .22,,mine is a SILVER STREAK .20,the top rifle is a Benjamin Franklin 342(1969) the other older ones are Sheridan Blue Streak .20,,,They are much better than the newer models,that was the reason I bought the bottom Silver Streak,just to compare to the older guns,they are good but no way near the quality of the old ones,my Sheridan shoots over 700fps with eight pumps .20!
