Hey, don't get annoyed with me - please! I'm 1000% sure I've posted
here since 2008! Maybe not on the RC Groups site though!
I only concerned myself with the outwards appearance of the anchor on my Graupner
Southampton, so I couldn't tell you where the chain goes on the inner side of the bulwarks, sorry. No insider information. Though Dad was a tug skipper for the last 17 years of his career, his (and my, for that matter) detailed knowledge of tugs was based on his charge for those years, the Newhaven tug
Meeching, plus the various relief tugs supplied by J P Knight -
Kent and
Kite most of the time.
As I said, I used an off the shelf Billings anchor with some fine jewellery chain that ran just behind the stock of the anchor - both sprayed black, of course. Wyeforce doesn't have the traditional anchor recess below main deck level, just what looks like a small recess above. I recreated this with just two small strips of plastic.
Not perfect or truly accurate, but much better than having no anchor at all! Although my Southampton is a smaller scale than the proper Wyeforce kit, I'm sure what I did would scale up OK.
Couple of photos attached. Hope they may give you some ideas. I'm sure you can improve on what I did. I know a lot more about modelling now than when I did this!
