On the Spear; I now have a set of drill bits again and should be able to get it drilled and replaced with wire. Because lets face it sending the part to a remote part of Australia is not likely to work too well. Thanks for the offer to replace though.
On the multipart thing; it is less that they are multipart than that I cannot reliably find out which ones are multipart without buying them. Miniatures that are shown in your store as single piece miniatures (Cocky Dragon Knight) turn out to be multipart and so on.
If I could know if they are multipart before I buy I might buy more, at worst I would be making an informed decision and not get frustrated by the arrival of multipart models that seemed to be single pieces.
