Hi Jeff...
well, I didn't get one of those boat mooring devices...you know, those that
begin with M or something...I got another South Bend, another hero of the north
Atlantic convoys, shipped over in 1942. It's a 13" model A in tip top
condition. The only drawback is the original American type toolpost, which is
barely worthy of the name really, though I'm told some SB useers swear bythem.
First project when my hand recovers will be to make up a decent four way.

"...due to ease of manufacture..." You're right about
that, all right!! That's true even in model sizes.
