Dave, I might have an update on the small wheelbarrow. The Open Salt Compendium, on page 261, has this to say about it:
...formerly considered the BARLEY pattern by Adams Glass Co., with very faint marks under the wheelbarrow Pat. Apld. For, c. 1882, is now believed to be the HORSESHOE pattern (also known as GOOD LUCK or PRAYER RUG), patented by James Dalzell, an officer of Adams and Company. It has been found in clear (most common), frosted, and more recently and very rarely in canary. Prices are $100 in clear, $125-150 in amber, and $280 in canary. (This information was noted in the first Open Salt Collectors National Newsletter published in 2001 and provifded by Ed Bowman, citing authors Steven D. Skeim and Dave Peterson, Editor of Vaseline Glass Collectors Inc.)
LOL! OK, I'm still going to post this but, boy, do I feel silly: it wasn't until I typed the attribution at the end that the penny dropped! I hope, at least, the Compendium got your details right.
