This is a good example of how the large surplus warehouses, like Numrich, have had their inventories depleted. Often their stock has been bought by small entrepreneurs who found a favorable spread between the buy and sell prices; they've bought the old stock and are parceling it out at places like eBay. Enfield magazines are a good example -- hard to find one under $50 anymore. If you are looking for a Mk III, send a PM to the eBay sellers who are peddling other stock parts like butts and hand guards -- one might show up.
It's getting to be time for someone with the proper machinery to start turning out fore-ends; seems there is a profit to be made based on supply and demand.

Just checked. Liberty Tree has them in inventory for $65
