Reconstructing History RH704 is a versatile pattern. I believe it has instructions for short sailor waistcoat, long waistcoat and sleeved waistcoats. I think she's in Europe now, but when I ordered last time it arrived quickly. There are some resellers too, might even find on eBay.

I can recommend this pattern, I've made both the sleeved and sleeveless versions. Sleeves on anything (shirts, waistcoats, jackets, coats) totally messes with me, but I've done it.
