HO scale group of Misc hardware - some missing - some unopened

This is simply a group of small hardware items that are being sold together as a group.

I am not familiar with what these are or how they are to be used 

The metal rail joiners have been opened and have some pieces missing

The insulated joiners seem to be unopened

The couplers have some packages opened and others unopened

The 2 packs of screws are unopened

Conditions: See photos

Box: No

These are some HO scale parts that our kids had when they were young.  I do not know anything about them and they are sold as is with no warranty of completeness or condition - 

These are being sold cheap so we do not support Returns on these items.

We have a sizable amount of this HO track and accessories, so mark us as a favorite to be notified of future listings.

We do combine shipping when possible so please add all the items you would like before check out for the best shipping charge.

Thanks very much.
