PM if you have one for sale. Regarding the Marble’s I’d go for a Improved or standard  with the 1/8″ ivory or red bead sight.  I want an ivory front on the 20 S, which is a 1/8″ bead sight.  As a note as some sights are unmarked, the 20 S would be .360″ tall, the Marble’s no. 2 is .312″, both should be about 5/8″ wide.

I’d go $150 for a minty pre-WWI example.

I have an excellent/minty no. 3 Improved to trade or several Ivory Lymans of various heights to trade, also.

Thanks!
