Pillars for Märklin tin - bridges - double version

The pillars for Märklin metal bridges and ramps( 7161, 7 162, 7163) are not useable for double bridges. Two pillars side by side are wider than the regular distance between two tracks in the standard geometry (77.4mm). So I designed these pillars which are similar to ones sold by Märklin between the late 1940s and 1970 but suitable for double - lines.

Edit 2020/12/28: Version with a groove for a regular single-pillar added. So bridges with two different heights can be build.
