While browsing through my archive, I've just stumbled upon the War Ministry's circular letter of 1904 concerning the wearing of spurs. As almost everything in Russia past and present, the matter turns out to be complicated and sometimes elusive.
For instance, of all Cossack formations only the officers of two Guards Cossack regiments and the Tsar's Cossack Convoy were allowed and obliged to wear spurs. However, when other Cossack officers were dispatched to St.Petersburg, Moscow or Warsaw, they also could wear spurs "so as not to feel inferior compared to their Guards comrades". But then they had to return to their units and therefore to be stripped of their spurs! The humane War Ministry, in appreciation of poor guys' apparent distress, kindly granted them a grace period - the length of which was left to consideration of their regimental commanders. Now, other officers of the same regiment could feel humiliated by not wearing spurs on par with their happier colleagues, so for the length of the above period - which in theory and in practice could be infinite - all officers could wear spurs if they wished so. However,... and so on and so forth.
But all this sophistication doesn't apply to you Iain. You're a general ain't you? All generals without exception had to wear spurs at all times, no matter what their wives thought of their furniture's fate. The good news is that the spurs' exact fashion wasn't prescribed, so it's up to your free choice.
