thats a tricky question , but my first impression is WOW WOW
but when I enlarge the pictures untill they start looking like squares Im not so sure anymore for some parts .
barrel is probably an original , or an extremely well made copy. if its an copy it would probably pass as an original at most museums around the world . my guts tell me the barrel is original , but its difficult to say without seeing it in real life .
hopefully it was an long time ago , but some time they seem to have used bees wax or some kind of clear cote on the barrel ,
cant say if its wax or clear cote , both of them have an yellowish tone when they are 150 years old . wax already when its newly made , but old clear cote got it when getting old . sorry if Im not use the correct word , but I hope you understand what I mean when saying clear cote , my english skills aint good enough sometimes .
when we come to the carriage it looks original at an first look , main body , the two long paralell boards are ok and all fittings of steel .
but when it comes to the axle and wheels Im not sure , my guess is that axle tree and wheels have been "new" made some 150 years ago or so , they seem to be in to good condition to be well over 300 years old . and its absolutely to much paint left on it . it doesnt fit together with the rest of the carriage in condition .
the wheels or tires or what you call it , the outer steel parts on the wheel . they look original to me when only looking at the photos .
but the bands crossing and holding the tire in place have an completely different surface structor , seems to be in an much better shape then the rest of the steel parts , same for some of the reinforcement rings to the wheel centers .
I would say that most of it is original , except for the wood in axle and wheels , and some of the steel parts .
but nothing is any newly made fake , the rebuild of the carriage was probably made early to mid 1800 as it was very popular to have antique weapons then at castles and mansions , same as with the knights armours , they was commonly produced then as the originals was to few , many of them are today sold as originals .
over all its an nice cannon
but this is just my thinkings and believes , hope there are more comments at this topic .
if any one have completely other ideas I hope to hear them , how else to learn anything .
Im not any cannon expert , I just use common sense when judging this cannon .
COME ON FOLKS , LETS HAVE SOME COMMENTS .
