AS a paramedic and a collector of ambulance service insignia, I am trying to locate certain cap badges to complete my collection, which to date numbers some 320 items.

One such badge that I hope to find was used by York City Ambulance Service from 1948 until 1974, when the service was amalgamated with North Yorkshire.

I believe the badge is a chrome cross which features the shield of the city, in coloured enamel, at its centre.

I wondered if any of your readers might be able to help me obtain one.
