Some of the many.....

I thought I would share some of the things one collects along the way L-R the projectile is a AN FA 4" 35lb missing the fuse (repro turned up for looks) and the driving band (repro fitted just for looks) driving bands were cut off after the war due to the shortage of copper.
2nd is the good ol Bofor 40mm round.
The 3rd one is a 30mm cycling round just to check the functioning of the weapon and feed system (Does the F-16 use these as we do not have A-10's in the RAAF)
4th is a 30mm round from what I may guess is from a bushmaster but I feel they are 25mm could be wrong but I am open to suggestions.
5th is a NESCO 20mm 1942 drill round guess for the Oerlikon or the Hispano Suiza for training as an AD with a 20mm would be pretty sad I guess.
Do not ask how I got them as there is 40+ years collecting stuff in the sulk room a bloke has to have I am running out of space.
From flea markets to fairs, swaps, 2nd hand shops, and that site years ago and been given stuff.
It is pretty hard & Expensive to get stuff like this in Aus not only because of our geographical location but also we do not have the shops and places that sell this gear I tried to get a full packet of 5 Kynoch 600NE here and it would have cost me the same as the rounds making each round $100.oo/ea

The 4"my brother brought home from the scrap dealer in his carry basket on his 28" bicycle before I was born it was our front door stop and cursed when you kicked it.
I ended up with it after my brother passed away suddenly so it has been in the family for 55+ years.
I used it as a training weight for free pistol holding it at arms length for 30 seconds(Just gripping it one handed was enough!) at a time to help with fatigue and getting used to holding for a long while for conditions unfortunately I found my Drulov was better than I was.
Anyway thought I would share this with you all...

P.S They are all inert guys
