Hi there ,
many thanks for starting an excellent thread .
i can only reply to a couple of questions but i hope it is of interest .
Regarding repro cloth insignia , much of the common stuff as you say has been copied , even trade badges now !! as i know of several UK based dealers who have large batches made up often in the far east they have plainly told me that if you can have a badge made up for $2.00 and sell it for $4.00 its worth doing if you do it big style in a couple of hundred lots , often when asked how come he has so many mint ,un issued ...say cloth Royal Engineers titles on his stall
" oh they came from an old tailors shop that was being pulled down ,found `em in the cellar " ...or the other good one is
" the guy that sold them to me was a Q.M at the depot ,and took them home at the end of the war as a keep sake " ......all 275 pairs

.
Many uk cloth /badge dealers that i have met over the years know that the average " punter " as we are known walking round an arms fair will not have a wad of cash to spend ( sorry to any of you millionaires out there ) they now know its easier to sell 10 items at $10.00 than one item at $100.
Many of the areas now being reproduced HOME GUARD /LAND ARMY /CD etc 15 years ago this would have been un heard of as there was no demand out side of a few hard core ...and forward thinking collectors !! but as the more
" sexy " areas go up in price or demand , collectors look for another cheaper area to collect to , in the 1980`s many british based collectors who were in to the german gear moved in to collecting US or brit stuff as they could no longer pay the prices that nazi items were reaching .
The yellow /blue pegasus signs that you know of were worn by one of the units attached to the britsh airborne 6TH FIELD FORCE in the 1970`s ..ish , i think but as they have the same colours as the R.A.S.C they are often passed of as a rare war time para unit
ref: the cloth TANK arm badge you have , i have been told

that the design around the gun barrel is not as detailed on an earlier pre 1920`s example but .....thats only what im told by a pal ....
regards ,MICHAEL.
