Looks like long Spanish stroke where the body rolls from side to side. The arms make a double overarmstroke and the legs two modified frog-kicks. The combination of the arms and legs is double long followed by a short gliding-phase with two arms stretched in front of the head.
On the left you see the first part of the swimming-stroke and on the right the second part.
Looks like the long thrust where the combination of the arms and legs is double short. This swimming-stroke is swum with a slightly longer gliding-period compared with the long thrust, with the arms in front of the head.
This swimming-stroke looks like the long thrust where the arms alternately acting as a trailing arm and a leading arm twice. This swimming-stroke is a nice historical variant.
