What a great project. There's a similar one going with a fellow from Oz interested in learning about the many Lithgowicon made SMLEs kicking around.

It's a long project, you won't be getting your details immediately, so patience and continuous updates are the go.

May I suggest, like Muffet chasing the SMLE info, that you publish an update table (spreadsheets are easy peasy for that) to show people the progress? It is a good way to motivate people to contribute.

Great project, well done in following your family history. Enjoy!
