I am looking for a score for Perosi's 'Missa in honorem Beati Ambrosii' (Mass in honor of St Ambrose). I downloaded the PDF score from IMSLP; but it's a full-color scan, and the original paper has yellowed. I was wondering if anyone had a cleaner copy (it was published my McLaughlin & Reilly Co. in the USA) that they could send me for my choir. (The 1895 printing from IMSLP is a little hard on the *older* eyes in the choir!)
