A question regarding a clan badge

[MacMillan of Rathdown]

I know very little about silver hallmarks! If you say it dates from the 1950s, I'll take your word for it. However, as it does not conform to the standard set forth for clan badges by your Chief, or the Standing Council of Scottish Chiefs, it isn't a pukka clansman's badge. Whether you choose to wear it (or not) is up to you.

I don't know if it does or not..I am still looking for answers. The web site for The Standing Council of Scottish Chiefs states the same paragraph as the Court of Lord Lyon (as I cited above).I have emailed some people from a few Heraldry societies and Clan officials I know, to ask the question and have drafted a letter to the Court of Lord Lyon. I am just really interested in finding the answer.
I just thought that the company you referenced above might have had a company stamp, I know a few do, as I can clearly see them on other pieces I have.
Thanks for your help,
Sara

Per Sheep in Wolf's Clothing request I have split this discussion regarding the particulars of Sara's cap badge to its own thread in the Tartan and Heraldry forum.
