ID Makers mark- Hammer and Axe heavy lead head & plaque

Another find from my brief car boot trip this morning! I thought ID on these would be easy with such a clear makers mark but it has so far eluded me!
A.I wants to attribute it to William Gould but I can’t find actual evidence of this mark being his but I may not be looking in the right place and AI is notoriously unreliable! They are really heavy, (the head is 1.3kg!) so is presumably made of lead. The mark is a crossed axe and hammer with R.T below one a crown above. Bumble has a registered design number sadly illegible.
Google gives me every axe and hammer in existence
Any ideas of maker, age or origin or where to look welcomed.
Many thanks

 

This is what could not be read on the Bumble disc ...

 

I think this is where that was found.

Rd 481726 I think that reads though maybe 181726 ?

 

I believe that Rd number would have been recorded in 1906.
