However, if one looks at the full description it states 'Marks - "No.69 I / N - AIR.42 / N.", on base', it also states that the exhibit was made and presented by Nally's Ltd., Sydney, 1944. Museums are sometimes the worst offenders for incorrectly identifying their exhibits, however Arthur de Ramon Penfold, a former industrial chemist was a curator and latterly a director of the museum. Penfold had a great interest in plastic and Nally it would appear made a large number of donations, thus one would like to think that the provenance can be accepted as correct.

The above attribution by the museum and the presence of "AIR" makes it all rather confusing. Nally did manufacture other ordnance items in bakelite.
