Bill, the two tins in the center, if the address is Hull, are the 'real', original Humbrol, and should be fine. They'll be at least five years old, and may need a lot of stirring, but should work fine. The tin on the right is the current stuff - might or might not work, but will not be as good as the original - and you can bet if you get another tin there'll be a difference in shade, or viscosity, or both!
I haven't seen the yellow cement containers in the UK, but perhaps my shop doesn't stock them. The design is new, but the cement wil not have been made by Humbrol, only the name being used, as the factory, and the company, no longer exist. I can't comment on the quality, as I no longer use the stuff , due to the original 'Britfix' cement being unavailable when the factory closed.I had to then use Revell, among others, which I still do.
Wojtek, I keep trying different tins of Humbrol, within an assortment of colours. Some work, some are poor quality, some work but are not the shade they're supposed to be, and so on. All the Humbrol metallics are of very poor quality, and very inconsistent.
I've placed an order with Hannant's for some frequently used colours from the Xtracolour range, which do work, and are superb. Unfortunately, they're out of stock of a couple I wanted, including two of the metallics, but I'll re-order when back in stock.
I'm also going to try a couple from the Model Master range, starting with metallics.
Unless Hornby improve the Humbrol paints (by finding a better manufacturer), then my days of using them, after 50 years, are over!
I was beginning to think I was perhaps being paranoid, but, talking to Iris, the owner of my LHS on Tuesday, she told me a number of her customers have commented on the paint. Also, she now only stocks the 'fast-moving', basic colours, which equates to about half the choice there used to be at this shop. I'm still working on trying to get her to stock an alternative enamel (she also stocks Tamiya acrylics), although she is restricted by various agreements with wholesalers etc.
