$10 Money Pit, 81mm Mortar
On a whim, I bought an 81mm mortar body off Coleman's for something like $10. Wasn't real happy when it arrived as they demilled the top by blow torch cutting it about 3/4's of an inch. So it sat here in my office for three weeks. Found fins for $50 and a fuse for $34 and a gas check for $5. So I'm maybe regretting this whole $10bargain but I have to say, it looks real cool. I just have the fins, not the fuse so I'll wait to post photos. After all this, I found a complete one for sale for about $30-$40 more than what I have in this pieced together one so I guess it's still a "bargain".
