US 40MM Brass Shell (Bofer Round) with Wooden Top-This would make for a great display piece. It is an INERT (of course) 40MM Brass shell. It measures 16 ½ inches (41.91 cm) tall with its gray painted wooden tip. This is very nicely marked and rare, dated 1945 on the bottom. This is also marked MK2 on the bottom. This is a great looking piece.
