I've just published photos of two very rare .22 sporters:http://rossrifle.com/forum/index.php?topic=777.0
These are rarely encountered. One is special order and I strongly suspect it was ordered as a mate to a Scotch Deerstalker. The other is a rare but known variation. It's primary features are the half-stock and a cresent style buttplate. I would dearly enjoy hearing (and ideally seeing) other half-stock .22 sporters. Actually, just hearing reports of other half-stock sporters that have been seen would be appreciated.
