Rudolfs Patent
RUDOLFS PATENT pipes appears to be a copy of a Peterson Patent in many respects. It has a VERY similar stamping style on the name, the arched wording, similar design of the R to the P in Peterson, with the word PATENT tucked in below the arched name, just like Peterson as well.
This example is hallmark dated to 1909, with Birmingham city marking. Under the name on the shank side is PRIMA, which is an early Comoy's grading from the same era, interesting enough. The stem appears to be what the Patent is applied to, but have no info as to the actual patent details. The stem tip is similar to a Peterson's P-lip in design, but with a wider flat center area, and dual forked draw holes, instead of the single hole of a Peterson. The tip is also similar to at BBB Glokar stem tip, also from the same era.
I found another example from a previous Ebay listing, to show similarity to the Peterson's stampings on the shank, and also includes more stamping showing on the top of the stem.
