Unserviceable carbon steel phosphated barrels

I am practicing some barrel work, and want to buy shot out or otherwise unserviceable carbon steel barrels. They must be 16” or longer, have .750 gas journals , and have no taper pin holes. I only want phosphated barrels, and those with gas journals in good condition.

I am offering $35, shipping included, for any barrel that meets these criteria. I need four of them.

I suppose it wouldn’t hurt if the barrel were serviceable, but I don’t imagine anyone would want to sell such for $35.
