Ok,
So thanks to some outstanding research by ccdjg, utilising some period literature, we now have some answers:
EG no.1 rifle we know already
EG no.2 rifle is the Columbia (later known as EG19)
EG no.3 rifle is a Gem type
EG no.4 rifle is probably the TB peerless rifle (Based on the timeline)
EG no.5 rifle is a crank wound gallery gun, (similar to an O.Will Kurbelspanner)
Then we have reason to believe the remaining 3 rifles might include:
A Bugelspanner
& A direct pull Mauser style kids trainer.
But we are not sure how they are numbered, 6, 7 or 8.
So that just leaves one left that is yet to be identified, let the hunt begin!
Many thanks to ccdjg’s fantastic research, greatly appreciated.
A more comprehensive breakdown of his research should be on Danny’s gallery shortly.
Cheers,
Matt
