I dont have the other parts (740 seems to be the old roadsign BL bb0139pb01c01/02 and 741 is just the redirect to 641)
But both transformers seem to be named after their respective sets (they are supplemental sets which contain just the transformers).
Both numbers are clearly embossed at the bottom.
The plug BLÂ bb0093a/bc01 fits both sets and is compatible with its newer version 2775c01. It is to connect the rail connector 511c01 or the automatic switch buttons (does anyone have them, they are missing yet).
Which number should that one have (didnt find one).
I already modeled the europlugs too.
