Hi Rob
If you come across any steel blacked chain that matches, the Dapol, Lionheart chain, could you please let me know as it is hard to find 7mm items here in Canada.
finding time for the hobby can be difficult at times. I hope you find time soon as I like to see what your next project will be.
The attached photo is my 7mm layout Gwendraeth.
Cheers
Michael
