Fantastic Chrome Plated 30" Beam Compass Machinist Hand Made- Extreme Quality

Description

Fantastically made, "30" Compass Chrome Plated by Fred Miller 2816 Liberty St. Easton, PA, BL, 2-8137" as the label inside states.
I have handled many machinist tools and I best describe this compass by comparison to production models made by companies like Starrett, Brown & Sharpe and Lufkin in a size that is about halfway between the Trammel Models that used .312 bars and the smaller Universal Divider types that uses a .216 bar, this compass being of a size that uses a .250 bar.
It's not a high production piece. Everything, and I repeat,....... everything on this set is hand machined to high tolerances right down to the screws. It is an absolute pleasure to hold and operate! There are springs inside the bar clamps to provide a smooth snug sliding action. There are even springs in the spinners to provide clearance for the clamps operate the snug clamps. (Not so on a Starrett which used shorter knurled spinners of fixed length posts.)
Fred, if that's who made this, did not put knurls on these parts. Instead, in my opinion, Fred machined the spinners, thumb screws and connectors using spline bar stock.(36 or 72 tooth.)
The connector fittings have a well designed metal spring concealed inside held in place by a slotted set screw in the middle of the fitting. The thumb screws are used to clamp against this spring instead of directly onto the bar to prevent scoring. The springs also orientate the flat to the screws to keep the bars in alignment. The connector fittings hold the rods firmly joined to create the 30" beam using  3 bars.
Bars are finely polished with rounded points. (See photos)
The compass point is reversible with a straight pin tip on each end.
Like I said, this is hand made by the machinist who put the name on a hand typed label inside the box. There are no other marking to be found.
In excellent condition with no pitting or rust. (Under high photo magnification I can tell that it could use a some cleaning.)
I am dating this to between 1963-1965 because of the zip code used on the address had a dash between the first digit that is for the state and the following 4 digits. The zip codes came out in 1963 and by 1965 the zip code was just 5 digits without using the dash.
The card stock box measures approximately 13" x 4" x 3/4" tall. Corners on the lid are split. Bottom is in excellent condition as shown.
The whole set weighs just under 1 lb.
