Vintage London Bobby Figurine: 1970s-80s Cast Metal UK Police Model

Solid metal cast model with 'London Bobby' engraved on base. Figurine dates from the early 1970s to early 1980s as the uniform retains the classic look (e.g. custodian helmet) but incorporates more modern equipment like the radio, reflecting the transition in policing tools during this period. It is heavy so unlikely to be aluminium - so potentially is lead or pewter. Total height with the base if 98mm with the figure alone 92mm tall. There is wear and tear on the figurine and I have made sure not to attempt to restoration. I cannot find another like this anywhere so it is either artisan produced or I would appreciate it if you know and can let me know.
