Hello Miko, and welcome to the forum. Great to have you aboard.
You've made your entrance with one of the rarest badges, that of the Polish 2nd Corps Armoured Cavalry Officers School (Szkoła Podchorążych Kawalerii Pancernej). The copies that have surfaced are well made, and coupled with the lack of genuine examples set a dangerous stage.
I'm sorry that your welcome here is not going to be greeted with a positive opinion on your badge. Posted below is a side by side comparison with a genuine example. Immediate difference is seen in the quality of translucent enamel through which the backing pattern of the cavalry pennon is visible. Picchiani & Barlacchi (P&B) and other period Italian makers of Polish badges were masters of quality enamelwork. Another unique characteristic of P&B badges is the brass threaded post with the characteristic thread ending on the tip. Look for this when assessing P&B products. On the reverse side note the "rivets" holding the parts together. P&B used wire prongs, which was a weakness of their badge construction often resulting in failure and separation of the parts. Hence the many solder repair jobs seen on original badges. Note that on your badge there are "cut" marks, yet no wires. Compare to the original badge. This suggests your badge was cast from an original. There are other troubling differences such as the numeral in the date 1946, the length of the pennon, surface finish, etc.
