I have a lot of oil bottles but there are certain aspects I do not know anything about. I recently purchased two Huffman oil bottles. There are differences and I wonder what the significances are. Is there value differences? Are there other sayings?

Bottle number 1: Has waves along the bottom and within the embossed Huffman name area it says "Equipment Fittings"

Bottle number 2: Has no waves along the bottom but does have fill arrows and says "Trustworthy Tools"

Thanks for any responses on this question. John
