Beautiful custom Richard Burton Jacket 50-52 like new

Beautiful custom jacket from Richard Bennett. Brown with a rust windowpane plaid pattern. No fabric label, feels like a 100% cashmere or a cashmere/wool blend. 4 buttons on sleeves. Back gussets and self belt. 3 internal and 3 external pockets. Looks unworn or hardly worn. I’m guessing this is a 50 or 52, it’s hard to measure due to the back gussets and generous front cut. See photos for my attempt at measuring and you can see the approximate measurement. Verify measurements before purchasing because I guessed at the size. Very high end jacket. Name label indicating “tailored for” will be removed before shipping.
