Polt Mart Ware?
I have a little ashtray I bought in England with a picture of a 'Rotary Cultivator' by Rickett 1858.
On the back there is a crown, the words in cursive "Polt Mart" or something like it and underneath, the words, WARE F.W.R. ENGLAND. I'm sorry I don't have the ability to send pictures. I wonder if anybody ever heard of the company.
