The Thomas M-3890 in this photo is my collection keeper. It was found this summer on a solo hunt and has an interesting story with a powerful lesson. I have added a top from a M-3250 I also dug this summer for comparison. Note that the top of the big M-3890 is nearly identical to the M-3250 "shawinigan" top and is just a scaled up version of the smaller top... Ralph Mershon was very stuck on this insulator design and designed both!! When I dug up this M-3890 I found the complete center but only parts of the top and base... not enough to make an insulator . The center was in the best condition of any I had ever found with 1/3 of the entire thing in one big part and the rest in only a few more large parts . When I went back to the location a few weeks later, I dug another spot and found the rest of the parts to complete an insulator about eight yards away, buried in a different location . Once again, the parts were remarkably large with the base split in maybe five parts and the top in six . Normally these are shattered into many dozens of parts . To make it even better .I found ALL of the parts to all three skirts and aside from a few small chips the insulator displays very nicely as is . Wile the color is a bit darker then some of these this one remains the best I ever found condition wise. For now, I am hanging on to it for my collection as I am running out of places to look for these. I may not find any more of them. This Thomas has the most exaggerated flare of any lilyshell skirt I have seen. The center skirt flairs out to a nearly horizontal plane .
