general question about regimental and school badges

[Mark McM]

Hi All,

As regards screw posts on Imperial regimental/school badges, is there a standard thread size generally used?

[Mark McM]

Anybody????

[Mathomhaus]

Probably not. I've been fortunate to have a couple dozen imperial regimental and award badges pass through my hands over the years and I found that very few screwplates proved to be interchangeable (although there was occasionally consistency in  threading among pieces manufactured by the same company or jeweler).

Regards

thanks!  Has any attempt ever been made to catalog the various thread sizes encountered?

Not that I am aware of, occasionally loose oddments appear in collection which I keep in a drawer in the hope that a they will fit a piece lacking screw plate or retaining nut.

Thanks, Paul!  Arcane subject matter, for sure!
