This is my grandfather. I scanned this photo and used Photoshop to clear it up and zoom in on the badges he is wearing. I searched sites that sold these badges to collectors to learn what I could. Can someone confirm or add any information - for example, the shoulder boards have no info? I find it curious he is not wearing his cap. The photo, I believe was taken in 1916 or 1917.
Belt buckle: Russian Imperial Guard
Badge on the pocket: Izmaylovsky Regiment
Badge on his collar: graduate of the Imperial State University in St. Petersburg? We know he graduated with a degree in railroad engineering. Are there lists of graduates anywhere that could confirm this?
Thank you in advance.
