Series I tail lamp reflector gasket +

Over the 30 year rebuild (!) I’ve lost some parts. Going back together now and while putting my nicely rechromed tail lights together I find the reflectors and associated brackets are gone. SNG has the main items (reflector and bracket) but I can’t seem to find where and how a gasket and spacer (on the stud?) fits. Probably the obvious under the perimeter of the reflector, but the picture of the NLA gasket shows a round cork disk. Maybe this will all be obvious once I get the 2 main parts, but some pictures would be nice if any one has them.

As a sad aside I probably threw them away as extra bicycle parts while fixing up bikes for the kid’s college use.

The nla parts are apparently avail. from the ‘old country’, as sng ordered them for me…
