Yeomanry buttons

[Riding shotgun]

Hi all

I would be greatful if anyone can help, I am looking for two 25mm Kings Crown Bedfordshire Yeomanry buttons, I am putting a tunic together (hence theprevious question on the shoulder titles) but have so far only managed to get three large buttons, i have plenty of the small ones and for now had to use later queens crown staybright buttons, there were quite a few coming up a while ago but they have dropped off again now, i have searched all the usual places on the internet but very little new coming up.

Thanks

Colin
