It is (it has to be) very late war modification likewise scissors on both sides (front and rear) of mainwheel legs.
All Czechoslovakian Avias S-92 and CS-92 had rectangular bulges and doubled scissors and all of them were just assembled from already made/manufactured parts (with only few internal modifications) - no new parts, no modifications of existing parts.
It is only my opinion, but Me-262 A in Dayton, Ohio indicates that not only Czech Avias had this shape of bulges and double scissors.
