Grenadier and Coldstream Guards with sliders

[Mike H]

Don't know if anybody has come across either of these yet, but both have been made by London Badge and Button Co Ltd with sliders rather than lugs.
Now the Grenadier Guards is the OR`s pattern not the cypher pattern. Obviously the Coldstream is the standard gold coloured cap star.

First query is this, has anybody come across the Grenadier Guards cypher pattern with a slider ?
Secondly, have the Scots and Irish guards been done too ?
