You've gotten a lot of good info and some valid opinions...

I've seen some ugly "sleevers" wearing English re-proofs. All the marks mean is the barrels didn't blow up on a particular day- they offer no guarantee of balance or regulation.

All guns (including sleevers) need to be judged on their particular merits. If a sleeved or gun, or one in need of sleeving, suits your plans, aesthetic, and wallet, go for it.

For my money, the poorest value will always be the gun with "borderline" barrels.

YMMV

Quite simply it is a cost option.

You have a gun with useless barrels so you cant sell it or use it. Your options in order of expense:

You can re-barrel it in England.

You can re-barrel it in Spain or Italy.

You can sleeve it to the best possible standards and have a proper barrel maker strike it up like a pair of new barrels and TIG weld the join to make it invisible.

You can sleeve it to average standard.

You can sleeve it cheaply.

Whatever choice you make will affect the outcome and the subsequent value of the gun.

The more expensive the gun to start with, the more value is affected by sleeving.

Sleeving is a practical, economical solution for getting more use out of older guns.

The better the sleeving work is, the better the bargain for the next owner.

It was a generaly held opinion of the trade .No one said that they would self destruct. It was simply that was how long people thought they would last . Some have'nt lasted that long others have lasted far longer . Some were done much better than others ,I have seen some realy bad jobs and some excelent ones . Like every thing else you got what you paid for ,some folk did'nt want to pay a lot.

The very reason sleeving came into existance at all was because people didn't want to pay a lot.
I was fortunate to know Mr. Christian Ashthorpe who is believed to be the inventor of sleeving, who sleeved a Mr. Herbert Sandals Purdey in 1948/49 for 15 which was about two weeks wages then.
Interestingly enough Purdey moved hell and high water to stop barrels from being sleeved, but eventually they got Christian to sleeve guns for them.

I am really impressed that the whole sleeving debate has moved on far enough that nearly every answer to this thread has been fair and reasonable.
A few years back you would have got little but abuse and invective!
In a way this is a good illustration of how the devaluing of sleeved guns has reduced to the point that a well sleeved gun is usually worth a lot more than one with sick tubes.
The exceptions are with 20g and 28g guns which are often used with their original barrels long after they should have been retired.
A high proportion of the guns I sell have been sleeved, usually TIG welded rather than soft-soldered, and I believe that, although each one is an individual, they all represent good value and are excellent shooters.
Of course I could sell them for more with good, original barrels but then I would have to pay a shed load more for them in the first place so I can offer them for what I consider sensible money.

Aren't "monobloc" barrels in essence sleeved?

I don't think so, Gnoman; not exactly anyway. While the process is the same, the term "monobloc" would mean a single forging comprising the chamber areas for both barrels (as well as the lumps) into which the two barrels are attached, while most sleeved barrels would involve chopper lump or other froms of original barrel maunfacture which are cut off just past the chambers and the replacement barrels attached...Geo

Thanks, George - but the point I thought was key is that the "new" barrels of a sleeve job are mechanically equivalent to those on a monobloc.

I might be wrong on this but if sleeved barrels fail in 25 years, is it the original chopper lump art that fails or the join?

If it's in the join then why won't monobloc construction fail the same way?

I think it's all BS. Use good glue and it will last forever. Only factory monobloc guns have been shown to be faulty, and they are glued with strange "stuff". Professionally sleeved guns have not been shown to fail, in my experience.
