Hi deejay

Sorry for the delayed response, I had just about forgotten about this post after other prioritys got in the way of the re-build over the last few months.
I took a bunch of photos this afternoon with intent to load them up tomorrow, and then decided to give the body another clean down with some degreaser and uncovered a plate with the model & serial numbers, it is a HK30.
Did a google search and came across another post on this site, another user has exactly the same: https://www.outdoorking-forum.com.au/forum/ubbthreads.php?ubb=showflat&Number=21282
At least now I have some good photos to work too
