Hi Jeremy,
Just a quick answer..... the low cost and lack of ability to make a profit is why Walsall do not make such items.
China and other Far eastern countries produce such items by the thousands, even hundreds of thousands... and I found several nice ones in China Town when I visited New York a few years back. With our Labour costs here, we just can not compete with the quality/price factor and then the distribution network needed to sell in sufficient quantities to turn a profit. In short, there are easier ways to make a living.
I have a few, just adding a little to the "theme" of my bonsai display area, also bought from a local store for about $6.
A search on e-bay or bT auctions will very often find these listed.
Best regards,
Ian.
