‘And then there’s the patina,’ Mr Boggins continued.
‘The what?’
He explained to them the meaning of this word as applied to furniture.
‘My dear friends, you’ve no idea the trouble these rascals will go to to imitate the hard beautiful bronze-like appearance of genuine patina. It’s terrible, really terrible, and it makes me quite sick to speak of it!’ He was spitting each word sharply off the tip of the tongue and making a sour mouth to show his extreme distaste. The men waited, hoping for more secrets.
‘The time and trouble that some mortals will go to in order to deceive the innocent!’ Mr Boggis cried. ‘It’s perfectly disgusting! D’you know what they did here, my friends? I can recognise it clearly. I can almost see them doing it, the long, complicated ritual of rubbing the wood with linseed oil, coating it over with French polish that has been cunningly coloured, brushing it down with pumice-stone and oil, beeswaxing it with a wax that contains dirt and dust, and finally giving it the heat treatment to crack the polish so that it looks like two-hundred-year-old varnish! It really upsets me to contemplate such knavery!’
The three men continued to gaze at the little patch of dark wood.
‘Feel it!’ Mr Boggis ordered. ‘Put your fingers on it! There, how does it feel, warm or cold?’
‘Feels cold,’ Rummins said.
‘Exactly, my friend! It happens to be a fact that faked patina is always cold to the touch. Real patina has a curiously warm feel to it.’
‘This feels normal,’ Rummins said, ready to argue.
‘No, sir, it’s cold. But of course it takes an experienced and sensitive finger-tip to pass a positive judgment. You couldn’t really be expected to judge this any more than I could be expected to judge the quality of your barley. Everything in life, my dear sir, is experience.’
The men were staring at this queer moon-faced clergyman with the bulging eyes, not quite so suspiciously now because he did seem to know a bit about his subject. But they were still a long way from trusting him.
Mr Boggis bent down and pointed to one of the metal drawer-handles on the commode. ‘This is another place where the fakers go to work,’ he said. ‘Old brass normally has a colour and character all of its own. Did you know that?’
They stared at him, hoping for still more secrets.
‘But the trouble is that they’ve become exceedingly skilled at matching it. In fact it’s almost impossible to tell the difference between “genuine old” and “faked old”. I don’t mind admitting that it has me guessing. So there’s not really any point in our scraping the paint off these handles. We wouldn’t be any the wiser.’
‘How can you possibly make new brass look like old?’ Claud said. ‘Brass doesn’t rust, you know.’
‘You are quite right, my friend. But these scoundrels have their own secret methods.’
‘Such as what?’ Claud asked. Any information of this nature was valuable, in his opinion. One never knew when it might come in handy.
‘All they have to do,’ Mr Boggis said, ‘is to place these handles overnight in a box of mahogany shavings saturated in sal ammoniac. The sal ammoniac turns the metal green, but if you rub off the green, you will find underneath it a fine soft silvery-warm lustre, a lustre identical to that which comes with very old brass. Oh, it is so bestial, the things they do! With iron they have another trick.’
‘What do they do with iron?’ Claud asked, fascinated.
‘Iron’s easy,’ Mr Boggis said. ‘Iron locks and plates and hinges are simply buried in common salt and they come out all rusted and pitted in no time.’
‘All right,’ Rummins said. ‘So you admit you can’t tell about the handles. For all you know, they may be hundreds and hundreds of years old. Correct?’
‘Ah,’ Mr Boggis whispered, fixing Rummins with two big bulging brown eyes. ‘That’s where you’re wrong. Watch this.’
From his jacket pocket, he took out a small screwdriver. At the same time, although none of them saw him do it, he also took out a little brass screw which he kept well hidden in the palm of his hand. Then he selected one of the screws in the commode – there were four to each handle – and began carefully scraping all traces of white paint from its head. When he had done this, he started slowly to unscrew it.
‘If this is a genuine old brass screw from the eighteenth century,’ he was saying, ‘the spiral will be slightly uneven and you’ll be able to see quite easily that it has been hand-cut with a file. But if this brasswork is faked from more recent times, Victorian or later, then obviously the screw will be of the same period. It will be a mass-produced, machine-made article. Anyone can recognise a machine-made screw. Well, we shall see.’
It was not difficult, as he put his hands over the old screw and drew it out, for Mr Boggis to substitute the new one hidden in his palm. This was another little trick of his, and through the years it had proved a most rewarding one. The pockets of his clergyman’s jacket were always stocked with a quantity of cheap brass screws of various sizes.
‘There you are,’ he said, handing the modern screw to Rummins. ‘Take a look at that. Notice the exact evenness of the spiral? See it? Of course you do. It’s just a cheap common little screw that you yourself could buy today in any ironmonger’s in the country.’
The screw was handed round from the one to the other, each examining it carefully. Even Rummins was impressed now.
Mr Boggis put the screwdriver back into his pocket together with the fine hand-cut screw that he’d taken from the commode, and then he turned and walked slowly past the three men toward the door.
‘Mr dear friends,’ he said, pausing at the entrance to the kitchen, ‘it was so good of you to let me peep inside your little home – so kind. I do hope I haven’t been a terrible old bore.’
