[Tex/LaTex] LaTeX font for ‘old-fashioned’ script characters

blackboard;charactersfontsmath-modemathcal

Browsing through a copy of Counterexamples in Analysis (Gelbaum & Olmsted), I'm quite enjoying the typeface used for 'script' letters (see links to examples below); visually it's somewhere between what I'd now call calligraphic and fraktur, and semantically it's used where now we'd use mathcal, mathfrak or mathbb.

I was therefore procrastinatiously looking for a LaTeX-usable font to include these characters, but couldn't seem to find any. I'm certain they're not unique to this text or publisher, so figured my lack of success was probably more to do with searching with the wrong keywords. If anyone has any ideas I'd be grateful.

F,G,P

N,Q,B,D,J(?)

Essentially these symbols seem to be available in the MathTime Professional 2 Fonts. In particular page 35 of the user guide gives a complete alphabet of "curly" capital letters including these symbols:

The following is a hack that seems to do the work, it actually comes from the source of the fourier package.

\documentclass{article}

\DeclareFontFamily{U}{futm}{}
\DeclareFontShape{U}{futm}{m}{n}{
  <-> s * [.92] fourier-bb
  }{}
\DeclareSymbolFont{Ufutm}{U}{futm}{m}{n}
\DeclareSymbolFontAlphabet{\mathbb}{Ufutm}

[Tex/LaTex] Typesetting old fashioned factorials

An implementation with "newschool" tikz:

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{calc}
\newcommand{\oldfactorial}[1]{%
\tikz[baseline]{\node[anchor=base,inner sep=0.3ex](mynode){\ensuremath{#1}};\draw(mynode.north west)--(mynode.south west)--(mynode.south east);\path[use as bounding box]($(mynode.south west)+(-0.3ex,-0.3ex)$)rectangle($(mynode.north east)+(0.3ex,0.3ex)$);}
}
\begin{document}
This is the old notation for the factorial $\oldfactorial{n}$. Some other text
in order to wrap the line and see what happens with interline spacing
below the symbol. It also works in subscripts
\[
X=\sum_{0\le i\le\oldfactorial{n}}A_i+\left(\oldfactorial{x^2}\right)
\]
Here's a big version:

{\Huge$\oldfactorial{n}$}
\end{document}
