I have had this fire extinguisher for years and figure it must have come off a toy I had when I was little, but it's the right scale and perfect for what I wanted.
Prior to using it, it did used to have a handle on the side so this was removed and smoothed over, and any marks in the surface filled and again sanded smooth, and once I was happy with the finish item I made a mould and casted a couple to check they came out ok.
A coat of appropriate coloured paint and bit of black rubber hose attached to the end, plus a small sticker on the front, just finished it off and it was ready to add to my truck.
These parts are for sale.
