I've been off the site for a while, but here goes.
It has no value, it is scrap metal. With the exception of WWII German, WWII Japanese and pretty much any grenades, the ebb and flow of collector interest is not high enough or consistent enough to establish real value. If you pay $200 for this piece today, can you get your money out of it tomorrow? Next month? Next year? Don't collect as an investment, collect because you love ordnance. Pay what it is worth to you, sell for what someone else will pay, don't look back on either.
Good to be back.
