I have a couple of variations of the colour celluloid one and 3 of the others, but never seen some of them before.
You have a great collection BIGGET, Well done
In regards to the celluloids.. I think I recall seeing 3-4 variations
the variations are the plating (gold or silver)
and the stamped design on the buckle frame (plain or with stamped design)
I purchased Marc Verstreats whole youth buckle collection in 2008 (over 200 buckles) and it cost me an arm and 3 legs... it was right after this that I was offered the sympathizer buckles and I just couldnt think of spending any more money at the time... I should have done it anyway!!
