They're really old imperial bricks.

From the original close-up photo, it looks more like cement-based re-pointing has been carried out at some time in the past due to the many fine cracks in the bed joints. It does look very light in colour - possibly done with either white cement, Portland cement with hydrated lime, a very light coloured sand or even overpainted? At worst case it could be efflorescence. I could be wrong but if you've got to match it, chip a bit off to check and see if the original mortar is revealed underneath (quite probably traditional lime-based).

No No I was wrong, they are metric bricks dating from around 1920 I think.

sorry brucie i got ya this time
almost certainly the main mortar is 16 sand 1 cement and 1 lime
but that pointing is original
the old brickies i worked with as a lad said they used to build in a super weak mix then go around after pointing
i would bet my eye teeth that that pointing is original inter war pointing
sorry eye tooth,waiting for implant :;):

LLL – when you mentioned lime in your first post I thought you was referring to a traditional lime sand mortar (with no cement) hence my comment. I haven’t seen a lime mortar crack to the extent shown in the photo so presumed it must contain cement (or a proportion of), this being much more brittle and prone to cracking than lime only. I must confess I haven’t come across a 16:1:1 mix before. Did they point after laying with a richer mix or use the same? It's weathered very well for 70 years or more in service. Your eye tooth could well be safe :D

its very typical of lots of inter war semis all over the south east,apparently cement was still very expensive in the 20-30s so was sparingly used in the mortar which was raked out every day
a stronger mix was used in the pointing mixture resulting in crazing as you see
pretty good for 80 years old though
the victorian stuff would be lime mortar then tuckpointed an art that i have a great deal of admiration for

Stacks up - cement was relatively expensive until the more modern, higher production kilns came on strong after the 2nd world war. Saw a bloke doing some tuck pointing a few years ago - as you say it's an art. From a distance you'd thought he painted the thin joint lines- all dead straight.
