You may have to collect images of the full set of numbers and hope they
are consistent then compare the details to available fonts. I'm sure
that metal number stamps can be had in most any font desired, but most
commonly are available in a Gothic font. At least the Gothic font is
what is offered in McMaster-Carr's catalog #107. They do have the
catalog on line these days www.mcmaster.com.

Many number sets used the same stamp for 6 and for 9.

The standards in 1963-'65 when I was working with panels at Collins was
that front panel silkscreen artwork used Copperplate Gothic and
component silkscreens used Leroy. Back panels, probably Leroy. The
feature of thee Copperplate Gothic was that it had tiny serifs that were
lost in the silkscreen but the forced the silkscreen to have sharper
outside corners.
