I agree, it is rather attractive
The one advantage is that the barrels can be changed without detracting from the appearance, as they are not engraved. I have it in a wood case complete with extra barrel, photograph shown below.
I prefer it to the later examples of Don's work on Webley pistols, as he covered them with a lot more engraving and had them refinished once completed. I've seen, and been offered a few of his later examples, but they weren't for me.
I would have liked a set of his Walnut chequered grips, but he told me he wouldn't make any separately as the cost would be prohibitive, but could be absorbed into the prices of his finished works, which at the time were around the £500 mark.
