Tap on my Shoulder I received an interesting letter, intended for Scribe a Line from Stuart Mcall, he wrote: I keep coming across taps & dies etc., carrying the name ‘The LAL Company (purporting to be made in England) but can fi  nd absolutely no reference to this Company on the Internet other than those associated with the sales of used tools. One reference thought it might be Langham, Archer & Lane of She  ffi   eld, but this again is a ghost-name as regards any Internet reference. I have become intrigued as to whether this was just a Trademark for another manufacturer. Any information would be appreciated but I fear those with knowledge may already have departed this life!  This was of particular interest to me as I have a very nice set of even-number BA taps and dies that used to belong to my grandfather. It is indeed a LAL set, but LAL stands for Lehmann, Archer, Lane Ltd. of Fairlop in Essex. Nearly all of the (carbon steel) taps and dies are srcinal, sadly the 2BA die has snapped. They still get some use despite their age, although I have another, full BA set that includes the odd numbers. The set is ‘No. 37’ and has taper and plug (no second) taps, fi ve 13/16” dies, a small but beautiful No. 182/0 tap wrench as well as a very nicely made diestock. Errata I’d like to apologise to readers confused or inconvenienced by the incorrect numbering on the cover of the last issue. Yes, the one with the ‘blue cover’ really was issue 252 despite the promi-nent ‘251’ in the corner. We also know that many readers rely on these corner fl ashes to help them fi nd the right copy in their archives, so here’s a ‘cut-out-and-keep’ triangle with the correct number on it for you to stick on the front of the last issue. An unrelated error was the inclusion in Is-sue 251 of a Greenwood Tools advert. The ad copy had a fl ash on for the Doncaster show with last year’s dates. Unfortunately, the advert should not have appeared and did so by mistake. This year’s Doncaster Show (the National Model Engineering and Modelling Exhibition is on the 12-14 May.    N  o .   2   5   2   ✄   Just a small selection from our current stock  ã Telephone enquiries welcome on any item of stock. ã We hold thousands of items not listed above. ã All items are subject to availability. ã All prices are subject to carriage and VAT @ 20%. ã We can deliver to all parts of the UK and deliver worldwide. ã Over 7,000 square feet of tools, machines and workshop equipment. telephone:  01903 892 510   ã  ã   e-mail:  sales @ Opening times: 9am -1pm & 2pm – 5pm Monday to Friday.
