Marklin Turnouts - Question about part numbers

What differences are there on these LH and RH Marklin manual turnouts?

Part numbers 8561 & 8564
Part numbers 8565 & 8566

Both pairs appear to be identical.

Thanks.

Unfortunately my 1994/5 catalog didn't have part numbers 8561 and 8564 but a little research came up with the following:

8561 - one pair of remote turnouts, one L and one R
8562 - one Left remote turnout
8563 - one Right remote turnout
8564 - two pairs of manual turnouts, two L and two R
8565 - one Left manual turnout
8566 - one Right manual turnout

To figure out 8561 and 8564, I found ebay listings with pictures of the turnouts and original packages so I think that I've got them right.

Correct, early on Marklin offered the turnouts in two-packs. Today these are only offered as singles. Besides the age of the turnout, there should not be too many differences between the circa 1970s two packs and today's singles.

Thank you for taking time to answer my question.

That explains it well. Thanks again.
