There are 3 different spigot for the M149. The old ones are hard to find. The newer replacement (same NSN) can be had on ebay look for "drum faucet" made by sette BF 3/4" is there P/N. I just got 4 and another SS'er got 2 so they are out there. Mcmastercar has them too but alot more $$.But these and the old ones are not for use with water any more go figure.
The new new ones look like a out door water faucet the NSN is 4510-01-433-0396 P/N is 12406415.
As for the lids I'm looking to. They still use the same tank and lid for the new M1112 so hope fullly some will show up some where. The box is the same too so just keep an eye out. If I find more than one I'll let you know. Right now I'm thinking of just making one my self. We'll see how that works out
If you find any thing eles for one let me know I need to redo mine.
