In response to a query by 'switch' yesterday here is a photograph of the 620 long delay demolition fuze. It is an Acetone-Celluloid fuze and was available in 12, 24 and 36 hour delays. There are two others in the series (Nos 600 and 610) which resemble artillery fuzes (for stock denial purposes etc).
If anyone has any of these they are not emotionally attached to I would be happy to give them a home.
