Following some really helpful feedback from Helen Geake (Time Team) I have re-worked this model replacing the lugs and pin with an assembly that I think would be closer to the original.
This model is based on a find by a metal detectorist featured in a Patreon only Time Team video. I have copied the form and detailing on the brooch as closely as possible. For those interested in Time Team they are carrying out new digs and creating programmes which go out on their YouTube channel. They are funded via Patreon so please do support them https://www.patreon.com/TimeTeamOfficial
You are free to use this model in any way.
