Nice pics and nice workshop.
Old Langskip....?
In the pictures I noticed the newer style cam chain tensioner (CCT). I'm not sure of the year they switched the tensioning parts but think it was at least a few years after '88. Do you know if someone changed the chain guides and put the new style CCT in there? The old style was a twisting plunger with a mushroom end and the new style is a ratchet type as you have pictured. As far as I have read the CCTs are not compatible with the different guide. You can't just "upgrade" to the newer one (although some of us consider it a down-grade).
Just concerned for you, that's all. If it sounds right, you're probably good. Maybe someone else will verify this for me.
This helps explain it...

It's potentially bad over a period of time (especially with road salt).
Sea water wasn't what i was hinting at.
