Back in 2014, I built this RT Models 100HP Sentinel for BRM.
It's a nice kit that comes complete with a bespoke motorising unit for slow running and all-wheel drive. Using a SPUD is all very well, but they need a lot of weight piled on top of them for slow running.
This is, to my eyes, a handsome beast. I recall Impetus kits producing one, complete with an impressive resin body, but by the time I could afford the price, the range had disappeared into one of those black holes from whence models never escape again.
Etched in nickel-silver, the RT Models version is an excellent replacement. I remember some of the bits were so small they didn't survive the etching process, but that also meant that they were so small I didn't miss them on the model.
