Spanish Plug Bayonet. Ricasso marked and (year) De 1856.The reverse side marked R.P. Blade is 10 ¼” long. Overall length 15 ¼”. Condition is good with one small chip out of the edge three inches from the point. Wooden hilt is very good, no chips, no cracks, no repairs. In our opinion this type of Spanish Plug bayonet is similar to those found in Mexico in the 1940’s and into the 1960’s. We base that on viewing several collections in the 1970’s and later in Mexico.
