It's been months since I found anything interesting locally to service and recently found several pens, two of which are a pair of MT&Co Swans.
One is a leverless 0160 and the other is a self filler SF 2.
I contacted The Pendragons regarding sizes but haven't heard back. I know the leverless needs a necked sac but I don't know what size and I don't know what size for the SF2 or if it needs a necked sac as well.
Any advice would be appreciated
