Machine Gun Regiment, Officers Hallmarked Silver Cap Badge

Officer's Guards Machine Gun Regiment HM, Birmingham 1918, Bent & Parker, a Superb officers example, of a very rare cap badge,  The enamel is missing and has been what looks like period replaced with red and blue velvet, In an ideal world I would have had this replaced however I think it looks just as nice as is and this looks like it was worn in this manner, I will get it done if the buyer requests that I do so, however it will add at least another £400 pounds to the purchase costs, you may get it done for a couple of hundred.
