Bucklers, pouches and misc weapons

20mm bases
Eccentric Miniatures is one of my favourite companies. I've gone on about their excellent "Great Crossbows" before - link.
More recently I decided to try their "By the Sprue" range. With the exception of the bases, each of the above sprues cost $2 US. (You get two of the bases sprues in a pack).
The top one is my personal favourite. The bucklers and pouches make it well worth the purchase price. I was considering getting bucklers made, but with this sprue available I can buy them for 25-cents each. Similarly, the pouches will be extremely useful.
Note that the longbow sprue has hands nocking arrows. So if you want to have arrows to stick in shields or the ground in front of your based figures all you have to do is snip the hands off. Note also that there are quivers of arrows but also a couple of bundles of arrows.
The weapon sprues might be useful for figure conversions. They are a bit plain for Tekumel and the hands are slightly small. One could snip the hands off and just use the weapon, however.
The bases are nice. Straight sides with an indented surface on one side and flat top on the other. The rounded corners may or may not be to your taste.
There are apparently plans to add to the range. A trebuchet was mentioned and I have been lobbying for an onager. :-)
A possible sprue addition that I think would be very popular would be light and heavy crossbows. One sprue for each. The heavy sprue could have winches to hang from the user's belt. :-)
