The gun has 6 rings shrunk on thick and wide. 
Diameter ofjoutside of’powder chamber about 7". 
Bore of powder chamber about 2^-". 
The gun appears 
to have a screwed 
on breech and 
possibly the powder 
chamber could be 
opened for loading- 
purposes as there is 
a cavity round the 
g u n which has 
rusted out to about 
the depth of 1^". 
Mr. Mitchell’s 
guns are of the 
same construction 
and in the breakage 
it can be seen that 
they were built up 
by longitudinal 
pieces of iron wel¬ 
ded together and 
then strengthened 
by the rings being 
shrunk on. 
I believe there 
are some similar 
guns in the Tower 
of London, but 
they are not so per¬ 
fect as the one I 
have got:— 
This gun is as 
old as any of its 
size in the Rotunda 
Museum and from 
the description and 
picture seems to be 
in a state of better 
preservation than 
many in that col¬ 
lection. In con¬ 
struction it some¬ 
what resembles gun 
No. 7, Class I., 
Rotunda Museum, 
though some two 
feet shorter than 
that gun and not of 
the same symmetri¬ 
cal shape and finish. 
Any information bearing on the gun or its probable history will be gladly 
received by the Secretary R.A.I.
