Well Lloyd I looked high for awhile and then low for awhile and even looked in the middle for awhile. So far I've not located the mould blocks. I have looked in all the usual places such an item "should" be hiding but I am infamous for putting stuff up for safe keeping and it taking me some long while to find again. I'm sure that's what's going on here.
One of my "usual" places is an old cardboard container that 15 lbs of Red Dot powder came in many long years ago, so many the label is so faded it's hard to tell it was Red Dot. I used to keep a bunch of moulds and handles in there but they are not there now, something else was in it. No doubt that means I found a supposedly safer place for what was there and when I figure where they somewhere is I'll get them headed your way.
Heck the way I am in looking for things one of the many I picked up may have been it and I just failed to correctly identify it as such. I was looking for a two cavity as that's what I thought it was but maybe I should look at the four cavity moulds a bit closer. If it was made in four cavity that might be what I have. I've not used it in a long time.
I suppose it's even remotely possible that "other fellow" we discussed might have borrowed it but I don't think so. I don't think I've ever loaned this one before.
