Bill:

Millwright’s Layout/Alignment Tools?  Another guess would be  Boilermaker’s
Layout Tools; they use beam compasses.

Starrett makes a 59F trammel set with interchangeable points, including
“scimitar shaped” points, which on first glance I think might fit right into
your case.

If you didn’t buy that unique toolbox, don’t be surprised if you end up with a
bad case of “non-buyer’s remorse!”  You’ll never see another one like it.

One of America’s greatest tool collectors, who shall remain nameless, once told
me that “We will regret the things we didn’t buy far more than the things we did
buy.
If you buy a regrettable item, you can probably recover at least part of the
money spent by reselling it. On the other hand, if you fail to buy something
that’s a once-in-a-lifetime opportunity, you’ll kick yourself forever.”

DAMHIKT is true! Turned down two in one very regrettable day! (It’s in the
archives, for those who might be interested. Search for keywords Stormville,
Norris, and Footprint)

Bill, my advice it to go for it!
