I get my Strelets figures from F and S who are based in Audenshaw not too far from Liverpool in fact near Manchester. Strange for the complaints to cluster as they would probably be distributed from Hannants. Hobbyists are very fuzzy on their rights and usually go to the manufacturer rather than the retailer. The retailer may be unaware of a fault whereas they could easily check with the customer in the shop and return the stock.
This is probably why Revell and Italeri put seals on their boxes.
Maybe my Strelets WWI Russian Cavalry is going to contain all horses when they arrive. Remember 1 sprue figures 2 sprue horses and no drinking on the job.
I have got many, far too many, boxes of Airfix, Hat, Esci, Matchbox and so on and never a mistake. I must be lucky so I better not tempt fate.
Liverpool is probably bad for collectors of Manchester United or Chelsea stickers in their cars.
Strelets has found a little Bermuda triangle or the Bootle triangle as it should be known.
I read your post this AM, then I went to my local hobby shop where I picked up a set of Dacians. Low and behold it contained three sprues of Dacians and one sprue of Ancient Germans! I'll be sending HaT an email.
